Utilização da videografia aérea na detecção de áreas com deficiências nutricionais em plantios de eucalipto. / The use of aerial videography in the detection of areas with nutricional deficiency in eucalyptus plantation.

Paulo Pompermayer Neto 26 March 2002 (has links)
A videografia aérea é uma técnica que vem sendo utilizada nos EUA para avaliação, detecção e prevenção de problemas na agricultura, agricultura de precisão e no manejo de áreas naturais. Um dos motivos para o emprego desta técnica é o seu baixo custo para a obtenção das imagens e a rapidez com que podem ser captadas, processadas e analisadas. Assim sendo, o objetivo deste trabalho foi verificar a utilidade da técnica videográfica no levantamento de problemas nutricionais em plantações de eucalipto, utilizando-a como ferramenta no monitoramento nutricional, tornando-o mais preciso e menos dispendioso que os métodos utilizados atualmente. Para isto, instalou-se um experimento com tratamentos de subtração de nutrientes com a finalidade de verificar a potencialidade da videografia aérea como técnica para distinguir os tratamentos com deficiência nutricional nos plantios deeucalipto. Foram obtidas imagens nos espectros verde, azul, vermelho e infravermelho próximo, 12 meses após o plantio. Essas imagens foram capturadas com duas câmeras S-VHS: uma capaz de captar a faixa do espectro visível (400 - 700 nm) e, outra capaz de captar a faixa do espectro visível mais infravermelho próximo (400 – 1100 nm). Nestas câmeras foram também utilizados filtros de subtração para separar as faixas do espectro a serem trabalhadas. Além disso, com a utilização do software ENVI, foi feita uma análise dos valores de pixels de cada parcela, obtendo-se os valores mínimos, médios, máximo e o desvio padrão da média. Estes valores foram, então, comparados e agrupados conforme análise estatística multivariada, buscando encontrar relações entre os dados das imagens e os tratamentos. Relações significativas entre os dados dendrométricos e os dados de pixel foram encontradas para as imagens obtidas a 1500 metros de altitude pela câmera COHU nos espectros azul e infravermelho próximo e, pela câmera PANASONIC no espectro vermelho. / The aerial videography is a technique that has been used in the USA to evaluate, detect and prevent agricultural problems, as well as in the handling of natural areas. One of the reasons for the employment of this technique is its low cost for obtaining the images and the speed with that they can be captured, processed and analyzed. The aim of this work was to verify the usefulness of the videography technique in detecting nutritional deficiency in eucalyptus plantations, using it as a tool in the nutritional monitoring, turning it more precise and less costly than the methods used at present. For this, an experiment was settled with treatments of subtraction of nutrients with the purpose of verifying the potentiality of the aerial videography as technique to distinguish the treatments with nutritional deficiency in eucalyptus plantation. Images were obtained in the green, blue, red and infrared close spectrum, after 12 months of plantation. Those images were obtained with two cameras S-VHS: one capable of capturing the bands of the visible spectrum (400 - 700 nm) and other capable of capturing the bands in the visible and near infrared band (400 - 1100 nm). In these cameras, subtraction filters were also used to separate the bands of the spectrum to work. Besides, with the use of the software ENVI, it was made an analysis of the values of pixels of each portion, being obtained the minimum, medium, maximum values and the mean standard deviation. Then, these values were compared to each other and put together according to the multivariate statistical analysis, looking for relationships between the data of the images and the treatments. Significant relationships between the tree and pixel values data were found for the images obtained in 1500 m high by the camera COHU, in the spectra blue and close infrared and for the camera PANASONIC, in the red band.

Videography on the Way to the Analytical Short Film: Managing the ambiguity in interaction regarding video material

Prantl, Daniel, Wallbaum, Christopher 23 July 2019 (has links)
This chapter gives a brief overview of research methods using video material, lead by the question how these manage the ambiguity lying in interaction regarding this footage. The argument is put forward that, from a perspective of symbolic interactionism, in order to adequately make assertions regarding video material it is necessary to use video itself as a key statement in scientific discourse.

Detecting the Presence of Disease by Unifying Two Methods of Remote Sensing.

Reames, Steve 05 1900 (has links)
There is currently no effective tool available to quickly and economically measure a change in landmass in the setting of biomedical professionals and environmental specialists. The purpose of this study is to structure and demonstrate a statistical change-detection method using remotely sensed data that can detect the presence of an infectious land borne disease. Data sources included the Texas Department of Health database, which provided the types of infectious land borne diseases and indicated the geographical area to study. Methods of data collection included the gathering of images produced by digital orthophoto quadrangle and aerial videography and Landsat. Also, a method was developed to identify statistically the severity of changes of the landmass over a three-year period. Data analysis included using a unique statistical detection procedure to measure the severity of change in landmass when a disease was not present and when the disease was present. The statistical detection method was applied to two different remotely sensed platform types and again to two like remotely sensed platform types. The results indicated that when the statistical change detection method was used for two different types of remote sensing mediums (i.e.-digital orthophoto quadrangle and aerial videography), the results were negative due to skewed and unreliable data. However, when two like remote sensing mediums were used (i.e.- videography to videography and Landsat to Landsat) the results were positive and the data were reliable.

Empathy and distanciation: an examination of Holocaust video- and photography in the Topography of Terror, the German Military History Museum and the Canadian Museum for Human Rights

Johnston-Weiss, Erin 12 September 2016 (has links)
This project seeks to examine the ways in which the media of Holocaust photography and videography are represented in museums in Canada and Germany. Specifically, this project analyzes the Topography of Terror (Berlin), the Canadian Museum for Human Rights (Winnipeg), and the German Military History Museum (Dresden). The media of video- and photography are integral to a comparative examination of the intentional and unintentional effects and knowledge produced by these museums, since both media tend to be seen as more ‘authentic’ than text and remain somewhat outside the control of the museums; photographs and videos are often more than just a mouthpiece for museal goals. In order to adequately compare these representations in each of the three museums, they are analyzed simultaneously through the lens of distance and proximity between visitor and subject, and whether one is able to feel empathy for historical persons (and with whom) or not. / October 2016

Symbiotic Catastrophes: An Urge To Make a Recording

Naïm, Denise Nicole 01 January 2007 (has links)
Becoming a young woman amid the foothills and valleys of the Appalachian Mountains has fulfilled me with an awareness that I am not from "around these parts" that I now find myself in. As I navigated my way across the mountains, to the southern slopes of the east coast, I began to realize the life I was leaving behind through the process of photography, film, and the act of making a recording. This document speaks about the ideas and persistent energy that drive my process of creation while focusing on three important bodies of work that exhibit what I believe to be a method of engagement between the body and the camera. Out of my experiences, I want to make record of the blips and intonations, and of the in-between spaces where language is displaced and the visual speaks for itself.

Uso de filmagem aérea em perspectiva no apoio à coleta de dados, na pesquisa, no ensino e na divulgação de informações em Geociências /

Sayeg, Heitor Siqueira. January 2007 (has links)
Orientador: Gilberto José Garcia / Banca: Sergio dos Anjos Ferreira Pinto / Banca: Arquimedes Peres Filho / Banca: Norberto Morales / Banca: Olavo Raymundo Junior / Resumo: Fotografia aérea NADIR é um conceito usado rotineiramente por geólogos e pesquisadores de vários campos de atividade. Filmagem aérea de baixa altitude, em perspectiva ou ortogonal, é um recurso muito acessível, pela qualidade e relação custo-benefício dos equipamentos digitais disponíveis, pela capacidade de processamento e facilidade de operação dos softwares e hardwares lançados no mercado e pelo custo da hora de vôo em aviões de pequeno porte. A visualização da organização das paisagens através de filmagens aéreas em perspectiva permite a construção de um banco de dados de fácil manuseio e fornece um ponto de vista complementar às informações derivadas de outras fontes. Os estudos e ações efetuados buscaram explorar essa técnica de registro de dados e testar seu potencial para compor material didático e transmitir informações específicas de interesse geológico. / Abstract: Vertical aerial videography is a commonly technique used by geologists and researchers from several fields of knowledge. Aerial videography of low altitude, in oblique viewing, is a resource not spread, but very accessible, by the quality of digital equipment available, by capacity and facility of software and hardware operation and by the low cost of flight hour in small planes. The terrain observation (imaging) and oblique visualization of landscape in TV language allow building data base, to promote discrimination of surface landforms and morphologic patterns with tectonic meanings, and supply an approach that supplement the information derived from other media. In this work the goal was to apply this technique of data register in low cost and complexity of data treatment, test its aptitude to compose the didactic material and transmit specific information from geological interest. / Doutor
