The work begins considering Google Street View as its media environment and we affirm that inflation and continuous dissemination of images by its apparatuses causes a anaestheticization of senses. The selected corpus of analysis was the photographic act of German photographer Michael Wolf in the series titled Street View, in which author takes photos, through computer screen, from Google Street View site. By this object, one analyzes the inventive and delved character of this photographic dynamic over the images, which one suggests an archaeological nature in this photographic act. By this point, the idea of an archeology of image is here evoked in the sense of depth perception, which points not only to past traces hidden in the depths of the image, but also prospect signal elements that indicate future tracks in it. Therefore, one justifies the need for this archaeological sight, as a way to overcome the celebrated superficial visuality in mediatic images, and our suggested hypothesis is that the archaeological tool, which is able to delve on the image is imagination. Consequently, imagination would operate as a point of equalization in front of saturated visual media environments. The methodology adopted was an approximation to the object, which took place oblique cuts and a broader target, one considers for an Archeogenealogy of concepts and theories. The research approaches aspects of Image Theory in Walter Benjamin, Aby Warburg, Hans Belting and Norval Baitello Jr., about media environments and how images in excess dulls perception, there was discussion with reflections of Theory of Media in authors like Vilém Flusser – concepts of reign of garbage and escalating of abstraction - Dietmar Kamper (imaginary orbit and force of imagination) and Malena Contrera, concept of mediasphere. Regarding the concept of imagination, one argues based on Bachelard, and about visual thinking we consider reflections from Arnheim and Damasio. As a result, therefore, we emphasize how imagination is configured as an archeology of image based on three aspects: thought by images, optical unconscious and distraction. Thereby, one reaffirms the fundamental role of the imagination, and thus the body, in its anthropological relationship with images / O objetivo central desta pesquisa é analisar se a imaginação pode se configurar como ferramenta arqueológica sobre a imagem em seus saturados ambientes midiáticos. O trabalho parte do cenário midiático do Google Street View e afirma que a inflação e disseminação contínua das imagens por meio de seus aparatos provoca um anestesiamento dos sentidos. O corpus de análise selecionado foi o ato fotográfico do fotógrafo alemão Michael Wolf na série intitulada Street View, na qual o autor registra, via tela do computador, imagens do site Google Street View. Por meio deste objeto, analisa-se o caráter inventivo e de escavação da imagem presente na dinâmica, o qual sugere uma natureza arqueológica neste ato fotográfico. Isso posto, a ideia de uma arqueologia sobre a imagem é aqui evocada no sentido de uma percepção aprofundada, que aponte tanto rastros passados escondidos nas profundezas da imagem quanto prospecte elementos que a sinalizem como reserva de um porvir. Justifica-se, dessa forma, a necessidade dessa visada arqueológica como modo de superar a visualidade superficial tão celebrada nas imagens midiáticas, e a hipótese sugerida é a de que a ferramenta arqueológica capaz dessa escavação sobre a imagem é a imaginação, a qual operaria como ponto de equalização frente aos saturados ambientes visuais midiáticos. A metodologia adotada foi a de um movimento de aproximação ao objeto, no qual realizou-se tanto recortes oblíquos, quanto visadas mais amplas, buscando-se considerar a Arqueogenealogia de conceitos e teorias. A pesquisa aborda aspectos da Teoria da Imagem em Walter Benjamin, Aby Warburg, Hans Belting e Norval Baitello Jr., sobre os ambientes midiáticos e o modo como as imagens em excesso neles embotam a percepção, dialogou-se com reflexões da Teoria da Mídia em autores como Vilém Flusser, conceitos de reino do lixo e escalada da abstração, Dietmar Kamper (órbita do imaginário e força da imaginação) e Malena Contrera (mediosfera). A respeito do conceito de imaginação, argumentamos com base em Bachelard e, sobre o pensamento por imagens, utilizamo-nos das apreciações de Arnheim e Damásio. Como resultado, portanto, salientamos o modo como a imaginação se configura como arqueologia da imagem baseada em três aspectos: pensamento por imagens, inconsciente ótico e distração. Assim, reafirma-se o papel fundamental da imaginação, e portanto do corpo, em sua relação antropológica com as imagens

The role and position of the documentary street photographer is examined in the context of other forms of contemporary visual survey, including Google Street View. The Street View methodology is critically examined and related to the methodologies of other visual artists, including street photographers Peter Black and Robert Frank. Comparisons are drawn between the methodological restrictions imposed by Street View and those imposed by the photographers in the course of their practice. The issue of authorship is discussed and the lack of specific authorship of Street View is related to its inability to augment the viewer's personal sense of space. Wainuiomata, a suburb of Hutt City in Wellington, New Zealand, is introduced as a location for the author's research into how documentary photography might operate. The author's own phenomenological history is considered, and it is proposed that Wainuiomata may act as a mirror which reflects a sense of place derived from personal history, triggered by the visual landscape. The author's installation work The 1 p.m. Project is discussed and contextualised as a response to the author's research findings.

Šiandien gausu technologijų, kurios suteikia galimybę paprasčiau bendrauti, dalintis informacija bei įspūdžiais, kitos, tikėtina, atlieka prevencinę funkciją prieš nusikaltimus, apsaugant mus ir mūsų nuosavybę. Tačiau tokia technologijų plėtra iškėlė grėsmę pačiam asmeniui, sumažindama teisę išlaikyti savo privatumą. Konkrečiau kalbant, turima omenyje tik tas technologijas, kurios susijusios su asmens atvaizdu ir jo paviešinimu. Viena iš tokių technologijų yra 2007 metų gegužę Jungtinėse Amerikos Valstijose pristatyta Google Street View paslauga – jos pagalba galima virtualiai keliauti po pasaulį ir matyti aplinką 360 laipsnių kampu. Pasirodžius minėtai paslaugai kilo didžiulis sąmyšis dėl intervencijos į asmens privatumą, nes įgyvendinant užmanytą šio projekto tikslą, kartu su gatvių ir pastatų vaizdais buvo užfiksuoti ir žmonės. Todėl šiame darbe pateikiama minėtos paslaugos ir jos poveikio asmens privatumui analizė. Pagrindinis darbo tikslas – išsiaiškinti, ar Google Street View pažeidžia teisę į privatų gyvenimą. Siekiant minėto tikslo pirmoje darbo dalyje analizuojama teisės į privatų gyvenimą samprata pagal tarptautinę ir nacionalinę teisę, toliau analizuojamas minėtos paslaugos įgyvendinimo atitikimas valstybių iškeltiems reikalavimams. Antroje darbo dalyje analizuojami du privatumo pažeidimo atvejai: gatvėje ir privačioje teritorijoje. Paskutiniame darbo skyriuje pateikiama atliktos apklausos analizė, kuria buvo siekta atskleisti privatumo vertinimo įvairovę Google...

The advancement of new technologies is changing the world, however, it raises the threat to the person by reducing his right to maintain his privacy at the same time. More specifically are meant only technologies that deal with person’s image and its disclosure. One of such technologies is Street View project of Google, which was introduced in May 2007 in United States of America. Street View makes possible to take a virtual travel around the world and viewing and navigating within 360 degree scenes of street-level imagery. Its realization caused huge commotion because of intervention to privacy – the cameras of Google vehicles captured images not only of buildings, automobiles but even passersby. The aim of this thesis is to ascertain whether Google Street View violates the right to the private life. The work is devided into three chapters. In first chapter of thesis the conception of the right to privacy according to international and national law is discussed. The realization of Google Street View under the standarts defined by States is also included into this chapter. The second one analizes two cases of privacy violation: on the street and in the private area. And in the third chapter the results of survey accomplished with... [to full text]

Cette recherche porte sur les manières dont les entités dominantes du web fabriquent le visible. Pour ce faire, la thèse examine les liens entre les aspirations utopiques de Google, Facebook et de la vision artificielle, les algorithmes spécifiques qu’ils développent, la relation qu’ils entretiennent avec les images, principalement photographiques, et leurs façons de moduler les visibilités. Afin de mener l’enquête sur les modalités de production, de présentation et d’acquisition du savoir visuel dans le web, l’approche théorique et méthodologique employée s’inspire de la sociologie de l’acteur-réseau, de l’étude féministe des sciences et inscrit des œuvres d’art dans le rôle d’analyseurs. L’œuvre hypermédiatique Image Atlas (2012) de Taryn Simon et Aaron Swartz installe l’examen de Google et de Google Images qui reconduisent les aspirations à l’accès universel, tandis que les captures d’écran de la série street view (2009) de Michael Wolf sont l’occasion de poursuivre l’étude de cette fonction photographique de Google Maps. L’exposition « After Faceb00k: Okanagan Valley » (2014) est le point de départ de l’examen de l’utopie facebookienne de la communauté planétaire. Le dépliage des éléments de l’œuvre vidéo The Future is Here! (2019) de Mimi Ọnụọha pose ensuite les éléments nécessaires à l’analyse du développement de l’apprentissage machine de la vision et des aspirations à l’automatisation radicale que ces programmes intensifient. Diverses modalités du visible sont ainsi mises au jour : la pertinence, l’autorité et la localisation, les affinités et le partage, la reconnaissance et la prédiction sont autant de stratégies par lesquelles Google, Facebook et la vision artificielle fabriquent le visible pour le rendre opérationnel plutôt que représentationnel. La thèse vient ainsi révéler, en suivant les œuvres, l’opérationnalisation de la photographie, en tant qu’objet et que notion, dans l’établissement et le maintien d’un capitalisme cognitif parasitaire produit par les assemblages sociotechniques à l’étude. / This research addresses on the ways in which internet's dominant entities fabricate the visible. To do so, the thesis focuses on the links between the utopian aspirations of Google, Facebook and computer vision, the specific algorithms they develop, the relationship they have with images – mainly photographic – and how they modulate visibilities. To investigate the modalities of production, presentation and acquisition of visual knowledge online, the theoretical and methodological approach used is inspired by the actor-network sociology, the feminist study of science, and inscribes artworks in the role of analyzers. Taryn Simon and Aaron Swartz's hypermedia work Image Atlas (2012) installs the examination of Google and Google Images that re-conduce aspirations for universal access. The screenshots from Michael Wolf's street view series (2009) are an opportunity to further investigate this Google Maps' photographic function. "After Faceb00k: Okanagan Valley" (2014) is the starting point for the examination of Facebook’s utopia of the global community. The unfolding of elements from Mimi Ọnụọha's video The Future is Here! (2019) then lays the groundwork necessary to analyze the development of machine learning of vision and the aspirations for radical automation intensified by these programs. Various modalities of the visible are thus uncovered: relevance, authority and localization, affinity and sharing, recognition and prediction. These are all strategies by which Google, Facebook and computer vision manufacture the visible to make it operational rather than representational. Following the artworks, the thesis thus comes to reveal the operationalization of photography, as an object and as a notion, in the establishment and maintaining of a parasitic cognitive capitalism produced by the sociotechnical assemblages under study.

Street View är en populär tjänst som ger mer information än traditionella karttjänster, men den ger också upphov till problem med integriteten. Populära kommersiella street view-tjänster misslyckas vanligtvis med att fullt ut skydda privatlivet för de personer som syns på bilderna. Ingen av dem tar heller hänsyn till integriteten för användare som laddar upp bilder. Å andra sidan är den nuvarande forskningen om preferenser för personlig integritet främst inriktad på sociala nätverk och ansiktsigenkänning. I och med utvecklingen av Mobile Crowd Sensing föreslår vi en tjänst för gatuvyer som bygger på frivilliga bidrag och som skyddar båda: anonymitet för användare som laddar upp bilder, och anonymitet och maximal integritet i verkliga livet för användare/egendomar i bilderna. Detta projekt bygger en säker och privat gatuvy som är mobilt användarvänlig och håller tillgänglighet. / Street View is a popular service providing additional information to traditional map services, but it also raises privacy concerns. Popular commercial street view services usually fail to fully protect the privacy of people in the pictures. In addition, none of them concerns the privacy of users who upload pictures. On the other hand, current research about privacy preferences mainly focuses on social networks and facial recognition. With the development of Mobile Crowd Sensing, we propose a Street View service based on volunteer contributions that protect both: anonymity of users who uploads pictures, and anonymity and maximum real-life privacy of user/properties in pictures. This project builds a secure and private street view which is mobile device friendly and keeps availability.

Brain-computer interface (BCI) or Brain Machine Interface (BMI) provides direct communication channel between user’s brain and an external device without any requirement of user’s physical movement. Primarily BCI has been employed in medical sciences to facilitate the patients with severe motor, visual and aural impairments. More recently many BCI are also being used as a part of entertainment. BCI differs from Neuroprosthetics, a study within Neuroscience, in terms of its usage; former connects the brain with a computer or external device while the later connects the nervous system to an implanted device. A BCI receives the modulated input from user either invasively or non-invasively. The modulated input, concealed in the huge amount of noise, contains distinct brain patterns based on the type of activity user is performing at that point in time. Primary task of a typical BCI is to find out those distinct brain patterns and translates them to meaningful communication command set. Cursor controllers, Spellers, Wheel Chair and robot Controllers are classic examples of BCI applications. This study aims to investigate an Electroencephalography (EEG) based non-invasive BCI in general and its interaction with a web interface in particular. Different aspects related to BCI are covered in this work including feedback techniques, BCI frameworks, commercial BCI hardware, and different BCI applications. BCI paradigm Steady State Visually Evoked Potentials (SSVEP) is being focused during this study. A hybrid solution is developed during this study, employing a general purpose BCI framework OpenViBE, which comprised of a low-level stimulus management and control module and a web based Google Street View client application. This study shows that a BCI can not only provide a way of communication for the impaired subjects but it can also be a multipurpose tool for a healthy person. During this study, it is being established that the major hurdles that hamper the performance of a BCI system are training protocols, BCI hardware and signal processing techniques. It is also observed that a controlled environment and expert assistance is required to operate a BCI system.

Objectivity and neutrality of current makers of online maps is hampered by the fact that the most important of them who form the public opinion are largely commercial giants. Sensitivity of approaches is desirable especially in specific situations involving territorial disputes. The textual part of the thesis brings theoretical insights to the problematics of map makers policies and their preservation or violation. At the same time is describes critical cartography as a current opposition against governmental and cooperative mapping, of which counter-mapping processes are regularly used in art, too. Practical outcome attempts to reflect specific approaches of map makers depending on particular territorial disputes. It takes place mostly in online environment, using the functions of Google Street View or Google Earth and forms of counter-mapping on the OSM platform. The goal is to bring alternative realities complicating map makers policies and governing apparatus to map projects with the international coverage.

Generative Adversarial Networks (GANs) is a deep learning method that has been developed for synthesizing data. One application for which it can be used for is image-to-image translations. This could prove to be valuable when training deep neural networks for image classification tasks. Two areas where deep learning methods are used are automotive vision systems and medical imaging. Automotive vision systems are expected to handle a broad range of scenarios which demand training data with a high diversity. The scenarios in the medical field are fewer but the problem is instead that it is difficult, time consuming and expensive to collect training data. This thesis evaluates different GAN models by comparing synthetic MR images produced by the models against ground truth images. A perceptual study is also performed by an expert in the field. It is shown by the study that the implemented GAN models can synthesize visually realistic MR images. It is also shown that models producing more visually realistic synthetic images not necessarily have better results in quantitative error measurements, when compared to ground truth data. Along with the investigations on medical images, the thesis explores the possibilities of generating synthetic street view images of different resolution, light and weather conditions. Different GAN models have been compared, implemented with our own adjustments, and evaluated. The results show that it is possible to create visually realistic images for different translations and image resolutions.
