O reconhecimento de padrões de movimentos tem se tornado um campo de pesquisa muito atrativo nos últimos anos devido, entre outros fatores, à grande massificação de dados em vídeos e a tendência na criação de interfaces homem-máquina que utilizam expressões faciais e corporais. Esse campo pode ser considerado um dos requisitos chave para análise e entendimento de vídeos. Neste trabalho é proposto um descritor de movimentos baseado em tensores de 2a ordem e histogramas de gradientes (HOG - Histogram of Oriented Gradients). O cálculo do descritor é rápido, simples e eficaz. Além disso, nenhum aprendizado prévio é necessário sendo que a adição de novas classes de movimentos ou novos vídeos não necessita de mudanças ou que se recalculem os descritores já existentes. Cada quadro do vídeo é particionado e em cada partição calcula-se o histograma de gradientes no espaço e no tempo. A partir daí calcula-se o tensor do quadro e o descritor final é formado por uma série de tensores de cada quadro. O descritor criado é avaliado classificando-se as bases de vídeos KTH e Hollywood2, utilizadas na literatura atual, com um classificador Máquina Vetor Suporte (SVM). Os resultados obtidos na base KTH são próximos aos descritores do estado da arte que utilizam informação local do vídeo. Os resultados obtidos na base Hollywood2 não superam o estado da arte, mas são próximos o suficiente para concluirmos que o método proposto é eficaz. Apesar de a literatura apresentar descritores que possuem resultados superiores na classificação, suas abordagens são complexas e de alto custo computacional.
The motion pattern recognition has become a very attractive research field in recent years due to the large amount of video data and the creation of human-machine interfaces that use facial and body expressions. This field can be considered one of the key requirements for analysis and understanding in video. This thesis proposes a motion descriptor based on second order tensor and histograms of oriented gradients. The calculation of the descriptor is fast, simple and effective. Furthermore, no prior knowledge of data basis is required and the addition of new classes of motion and videos do not need to recalculate the existing descriptors. The frame of a video is divided into a grid and the histogram of oriented gradients is computed in each cell. After that, the frame tensor is computed and the final descriptor is built by a series of frame tensors. The descriptor is evaluated in both KTH and Hollywood2 data basis, used in the current literature, with a Support Vector Machine classifier (SVM). The results obtained on the basis KTH are very close to the descriptors of the state-of-the-art that use local information of the video. The results obtained on the basis Hollywood2 not outweigh the state-of-the-art but are close enough to conclude that the proposed method is effective. Although the literature presents descriptors that have superior results, their approaches are complex and with computational cost.

Full textIn this work, the molecular-beam epitaxial growth and properties of ferromagnets, namely Fe and Fe_3Si are studied on low-symmetric GaAs(113)A substrates. Three important aspects are investigated: (i) growth and structural characterization, (ii) magnetic properties, and (iii) magnetotransport properties of Fe and Fe_3Si films on GaAs(113)A substrates. The growth of Fe and Fe_3Si films is optimized at growth temperatures of 0 and 250 degree Celsius, respectively, where the layers exhibit high crystal quality and a smooth interface/surface similar to the [001]-oriented films. The stability of Fe_(3+x)Si_(1-x) phase over a range of composition around the Fe_3Si stoichiometry is also demonstrated. The evolution of the in-plane magnetic anisotropy with film thickness exhibits two regions: a uniaxial magnetic anisotropy (UMA) for Fe film thicknesses = 70 MLs. The existence of an out-of-plane perpendicular magnetic anisotropy is also detected in ultrathin Fe films. The interfacial contribution of both the uniaxial and the perpendicular anisotropy constants, derived from the thickness-dependent study, are found to be independent of the [113] orientation and are hence an inherent property of the Fe/GaAs interface. The origin of the UMA is attributed to anisotropic bonding between Fe and As or Ga at the interface, similarly to Fe/GaAs(001). The magnetic anisotropy in Fe_3Si on GaAs(113)A exhibits a complex dependence on the growth conditions and composition. Magnetotransport measurements of both Fe(113) and Fe_3Si(113) films shows the striking appearance of an antisymmetric component (ASC) in the planar Hall effect (PHE). A phenomenological model based on the symmetry of the crystal provides a good explanation to both the ASC in the PHE as well as the symmetric anisotropic magnetoresistance. The model shows that the observed ASC component can be ascribed to a second-order Hall effect.
