Book Description
This brief focuses on two main problems in the domain of optical flow and trajectory estimation: (i) The problem of finding convex optimization methods to apply sparsity to optical flow; and (ii) The problem of how to extend sparsity to improve trajectories in a computationally tractable way. Beginning with a review of optical flow fundamentals, it discusses the commonly used flow estimation strategies and the advantages or shortcomings of each. The brief also introduces the concepts associated with sparsity including dictionaries and low rank matrices. Next, it provides context for optical flow and trajectory methods including algorithms, data sets, and performance measurement. The second half of the brief covers sparse regularization of total variation optical flow and robust low rank trajectories. The authors describe a new approach that uses partially-overlapping patches to accelerate the calculation and is implemented in a coarse-to-fine strategy. Experimental results show that combining total variation and a sparse constraint from a learned dictionary is more effective than employing total variation alone. The brief is targeted at researchers and practitioners in the fields of engineering and computer science. It caters particularly to new researchers looking for cutting edge topics in optical flow as well as veterans of optical flow wishing to learn of the latest advances in multi-frame methods. /div

Book Description
Muitos sistemas biológicos utilizam visão como forma primária de sensoriamento. Ao longo de milhões de anos de evolução, as diferentes espécies vêm demonstrando opotencial associado à capacidade de visão. A partir da década de 60, foram iniciados os primeiros estudos no sentido de proporcionar às máquinas esta forma de sensoriamento. A esta nova forma de sensoriamento dá-se o nome de Visão Computacional. Em Visão Computacional, muitos casos requerem a determinação de um campo vetorial que descreva os deslocamentos ocorridos entre dois quadros consecutivos de uma seqüência genérica de vídeo. A este campo vetorial dá-se o nome de Optical Flow (FluxoÓtico). A determinação do Optical Flow é ainda um problema sem solução. No presente trabalho, propõe-se um novo estimador estatístico para a determinação do Fluxo Ótico. Este estimador possui complexidade O(n) e associa um grau de confiabilidade a cada estimativa realizada. É aplicável a qualquer sinal digital (não apenas imagens ou vídeo, mas também a som, volume, etc) e vem demonstrando esultados muito promissores.
