Video sub-pixel frame alignmentZetterberg, Zackeus January 2024 (has links)
Video stabilization is an important aspect of video processing, especially for handheld devices where unintended camera movement can significantly degrade the resulting recording. This paper investigates four image based methods for video stabilization. The study explores the Lukas-Kanade, Inverse Compositional Lukas-Kanade, Farnebäck Optical Flow, and GMFlow methods, evaluating their sub-pixel accuracy, real-time performance, and robustness to in-frame motion such as a person walking in front of the camera. The results indicate that while all methods achieve sub-pixel precision, real-time execution on a mobile phone is not feasible with the current implementations. Furthermore, the methods exhibit varying levels of difficulty in handling in-frame motion, with RANSAC-based approaches partially compensating for non-camera-induced movement. The paper also discusses the potential of machine learning techniques, represented by GMFlow, in enhancing stabilization quality at the cost of computational complexity. The findings offer valuable insights for the development of more efficient and robust video stabilization solutions.

Quantitative Retrieval of Organic Soil Properties from Visible Near-Infrared Shortwave Infrared (Vis-NIR-SWIR) Spectroscopy Using Fractal-Based Feature Extraction.Liu, Lanfa, Buchroithner, Manfred, Ji, Min, Dong, Yunyun, Zhang, Rongchung 27 March 2017 (has links) (PDF)
Visible and near-infrared diffuse reflectance spectroscopy has been demonstrated to be a fast and cheap tool for estimating a large number of chemical and physical soil properties, and effective features extracted from spectra are crucial to correlating with these properties. We adopt a novel methodology for feature extraction of soil spectroscopy based on fractal geometry. The spectrum can be divided into multiple segments with different step–window pairs. For each segmented spectral curve, the fractal dimension value was calculated using variation estimators with power indices 0.5, 1.0 and 2.0. Thus, the fractal feature can be generated by multiplying the fractal dimension value with spectral energy. To assess and compare the performance of new generated features, we took advantage of organic soil samples from the large-scale European Land Use/Land Cover Area Frame Survey (LUCAS). Gradient-boosting regression models built using XGBoost library with soil spectral library were developed to estimate N, pH and soil organic carbon (SOC) contents. Features generated by a variogram estimator performed better than two other estimators and the principal component analysis (PCA). The estimation results for SOC were coefficient of determination (R2) = 0.85, root mean square error (RMSE) = 56.7 g/kg, the ratio of percent deviation (RPD) = 2.59; for pH: R2 = 0.82, RMSE = 0.49 g/kg, RPD = 2.31; and for N: R2 = 0.77, RMSE = 3.01 g/kg, RPD = 2.09. Even better results could be achieved when fractal features were combined with PCA components. Fractal features generated by the proposed method can improve estimation accuracies of soil properties and simultaneously maintain the original spectral curve shape.

Previous issue date: 2012-12-13 / This paper seeks to study the text of Lk 6, 20-26, of the beatitudes and of the woes, seeing in this passage an example of the recuperation, analysis and recreation of Jesus words. In this resides one of the particularities of this text in the context of the New Testament, which places it, however, in the heart of a fundamental direction of the beginnings of Christianity, namely, the tradition that goes back to Jesus by the conservation and transmission of his teachings.
The author of this paper proposes the study of this text in three aspects. The first is the study of the text in of itself, as a communicative unity. The second aspect is the verification of the literature that influenced the Lucan author in the construction of this text, especially the Q source, and its comparison with words of the beatitudes attributed to the poor present in the Gospel of Thomas and the letter of James. In the third aspect, the author s intention is to analyze the importance of the writer of the Lucan text, his interference and the use of the blessed are and the woe to for the community. He considers that one of the accomplishments of the beatitudes is the approximation to the table as the instauration of the Kingdom of God, that is, the rich who share their wealth with the beggars. In this way, it is possible to verify an important connection between sharing with the beggars and belonging to the community, as a key element to becoming part of the Kingdom of God, the central element Jesus life and preaching, proposed by the beatitudes according to Luke / A presente pesquisa se aproxima do texto de Lc 6,20-26, das bem-aventuranças e dos ais, vendo nessa passagem um exercício de recuperação, análise e recriação de palavras de Jesus. Aí está uma das particularidades deste escrito dentro do Novo Testamento, que o coloca no seio de uma vertente fundamental dos inícios do cristianismo, isto é, a tradição que se vincula a Jesus pela conservação e transmissão de seus ensinamentos.
O autor desta pesquisa propõe o estudo deste texto percorrendo três aspectos. O primeiro é o estudo do texto em si, como uma unidade comunicativa. O segundo consiste em verificar a literatura que influenciou o autor lucano na construção deste texto, especialmente a fonte Q, e a comparação desta com termos das bem-aventuranças atribuídas aos indigentes presentes no evangelho segundo Tomé e na carta de Tiago. No terceiro a proposta do autor é analisar a importância do redator do texto lucano, a sua interferência e o uso das bem-aventuranças e dos ais para o seio de sua comunidade. Considera que uma das realizações das bem-aventuranças é a aproximação da mesa como símbolo da instauração do Reino de Deus, isto é, a partilha dos bens dos ricos com os mendigos. Assim se verifica uma grande conexão entre o partilhar com os mendigos e a pertença à comunidade, constituindo um elemento-chave para fazer parte do Reino de Deus, elemento central da vida e pregação de Jesus proposto pelas bem-aventuranças segundo Lucas

Productivity growth and international capital flows in an integrated world / Croissance de la productivité et flux de capitaux internationaux dans un monde intégréLy-Dai, Hung 09 March 2017 (has links)
La mondialisation financière des dernières décennies témoigne du phénomène du déséquilibre mondial dans lequel les comptes déficitaires actuels de certaines grandes économies avancées sont continuellement financés par certains pays en développement avec des taux de croissance élevés et des stocks de capitaux rares. Sur le plan théorique, le modèle de croissance néoclassique implique qu’une économie avec une pénurie de capitaux aurait un produit marginal élevé de capital et un taux d’intérêt élevé d’autarcie. Par conséquent, lors de l’intégration avec la capitale mobile gratuite, ce pays éprouverait les entrées nettes de capitaux nets afin que le taux d’intérêt domestique soit égal au reste du taux mondial (Lucas 1990). De plus, une économie qui se développe plus rapidement que le reste du monde aurait également une demande d’investissement plus élevée et devrait connaître les entrées de capitaux totaux nets (Gourinchas and Jeanne 2013). Les déséquilibres mondiaux sont le résultat de l’hétérogénéité des tendances de l’épargne et des investissements dans tous les pays. En effet, un pays connaît un apport de capitaux si son économie est inférieure à son investissement : ce pays emprunte au reste du monde si sa sauvegarde est supérieure à son investissement. La thèse emploierait la croissance de la productivité pour afficher les sources de lumière sur cette hétérogénéité entre les pays. [...] / The financial globalization for the past decades witnesses the global imbalance phenomenon on which the deficit current accounts by some large advanced economics are continuously financed by some developing economies with the high output growth rates and the scarce capital stocks. On the theoretical ground, the Neo-Classical growth model implies that one economy with scarcity of capital would have a high marginal product of capital and a high autarky interest rate therefore, at the integration with the free mobile capital, that country would experience the net total capital inflows so that the domestic interest rate equals that to the rest of world’s rate (Lucas 1990). Furthermore, one economy growing faster than the rest of the world would also have a higher investment demand and should experience the inflows of net total capitals (Gourinchas and Jeanne 2015). The global imbalances are the result of the heterogeneity in the patterns of savings and investments across countries. Indeed, one country experiences an inflow of capital if its saving is less that its investment: that country borrows from the rest of the world to finance the excess investment demand. Similarly, one country would lend to the rest of the world if its saving is higher than its investment. The thesis would employ the productivity growth to shed the refresh lights on this heterogeneity across countries. [...]

La théâtralité dans l'œuvre de Lucas FernándezColl Sansalvador, Andreu 15 December 2007 (has links) (PDF)
C'est un lieu commun de la critique que d'attribuer à Lucas Fernández, avec son maître Juan del Encina, la co-paternité du théâtre en langue castillane. Malgré cette place honorable dans l'histoire littéraire, rares sont les études à avoir tenté de mettre en lumière ce qui fait la spécificité même de son œuvre, à savoir sa théâtralité. Ce travail de thèse a comme objectif d'explorer le vaste champ de la théâtralité à travers la mise en relief du fonctionnement dramaturgique des pièces qui composent les Farsas y églogas (Salamanque, 1514), le seul recueil de pièces de cet auteur qui soit parvenu jusqu'à nous. Ainsi commençons-nous par l'analyse des potentialités du texte dramatique en termes de gestuelle et plus largement, de communication non verbale, domaine englobant des signes hétérogènes comme le corps du personnage, les regards échangés, les attitudes physionomiques ou les déplacements. Nous poursuivons par l'étude du cadre de la fiction dramatique, en portant une attention particulière à la façon dont les oppositions spatiales concourent à doter les pièces de leur signification globale. Enfin, notre travail s'achève sur la description des mécanismes d'écriture du dialogue dramatique, en s'inspirant des apports méthodologiques de l'analyse du discours, et tout particulièrement de l'approche pragmatique et énonciativiste. Ce dernier versant de l'étude nous permet, par l'exploration de ce que Michel Vinaver appelle la « surface » des répliques, de montrer la variété des stratégies dramatiques de Lucas Fernández, dont l'œuvre, au-delà du primitivisme qu'on lui attribue du fait de ses intrigues réduites, s'avère résolument ancrée dans un « théâtre de la parole » aux accents particulièrement modernes.

Previous issue date: 2002-12-31 / The following research, offers a reading of the studies accomplished at the
Hospital e Maternidade Jardim América, in Goiânia-GO, during the period of January
2000 to January 2001. The main reason for this search was the observations done with
in-patients stay at several hospitals and that have presented different behaviors in the
on going of the hospitalization period. These patients, most of the time, have changed
their attitudes when they had received visitors that tried to comfort them with words and
religious prayers. These patients have started to cope more and more with the
therapeutics proposal and, this way, they early found the cure.
In this present study we have tried to divide our work in four parts. Firstly,
we provide a theoretical referencial that, we hope, might help and give subsidies to the
patients in their incentive psychotherapy. Also, we try to lead these patients to find a
certain sense in their lives. Then, it follows the interpretation and the anthropological
analysis of the biblical texts and of how these people can understand them and, also
use their message to improve the quality of their lives in the reality of these days . We
continued our studies with the reading of how the patients face the disease, the pain and
the suffering within an hospitalar institution. And to conclude our research, based on the
texts of Luke s Gospel, mainly in the prodigal son s parable ( Lk 15: 11-32); we place
Jesus Christ as the center of our life s project, for He was the One responsible for
disseminating love, compassion and mercy through all the mankind. / A pesquisa em questão oferece uma leitura dos estudos realizados no Hospital e
Maternidade Jardim América, de Goiânia-GO, no período de janeiro de 2000 a janeiro
de 2001. A principal busca por esta pesquisa foram as observações feitas em pacientes
que se encontravam internados em diversos hospitais e que apresentavam
comportamentos diversos no decorrer do período de hospitalização. Estes, na maioria
das vezes, mudavam as suas atitudes mediante visitas de pessoas que procuravam
confortá-los com palavras e orações religiosas. Os pacientes passavam a cooperar
cada vez mais com a terapêutica proposta e, assim, encontravam a cura precocemente.
Neste presente estudo procuramos dividir o nosso trabalho em quatro partes.
Primeiramente apresentamos um referencial teórico que possa ajudar e dar subsídios
aos pacientes na sua psicoterapia de incentivo. Fazendo, os mesmos, a encontrarem
um determinado sentido em suas vidas. Depois, a interpretação e a análise
antropológica dos textos bíblicos e de como estas pessoas podem entender e melhorar
a qualidade de suas vidas na realidade dos dias de hoje. Prosseguimos os nossos
estudos com a compreensão de como os pacientes encaram a doença, a dor e o
sofrimento dentro de uma instituição hospitalar. E para finalizar nossa pesquisa,
baseada no evangelho de Lucas, principalmente na parábola do filho pródigo ( Lc
15:11-32); nós colocamos Jesus Cristo como o centro do nosso projeto de vida, pois ele
foi o responsável em disseminar o amor, a compaixão e a misericórdia por toda a
humanidade.
