Optical Flow Estimation Using Discontinuity Conforming Filters
The discontinuities and the large image displacements pose some of the hardest problems in flow estimation. This paper uses a set of filters that change shape to avoid blending of the constraints across discontinuity boundaries. This is done by using an incompatibility measure of the constraints of neighbouring pixels. The algorithm is embedded in a coarse to fine multigrid scheme to address th...
متن کاملDepth-Discontinuity Preserving Optical Flow Using Time-Multiplexed Illumination
In the last 25 years optical flow has become more and more important in the field of Computer Vision. Many algorithms have been published since the first paper in 1981 and a lot of concepts have been introduced facing problems which occur when the pixel displacements between frames are determined. Even though todays algorithms explicitly consider violations of their model assumptions, they stil...
متن کاملRobust Discontinuity Preserving Optical Flow Methods
In this work, we present an implementation of discontinuity-preserving strategies in TV-L1 optical flow methods. These are based on exponential functions that mitigate the regularization at image edges, which usually provide precise flow boundaries. Nevertheless, if the smoothing is not well controlled, it may produce instabilities in the computed motion fields. We present an algorithm that all...
متن کاملFast two-frame multiscale dense optical flow estimation using discrete wavelet filters.
A multiscale algorithm with complexity O(N) (where N is the number of pixels in one image) using wavelet filters is proposed to estimate dense optical flow from two frames. Hierarchical image representation by wavelet decomposition is integrated with differential techniques in a new multiscale framework. It is shown that if a compactly supported wavelet basis with one vanishing moment is carefu...
متن کاملMoving Objects Segmentation Using Optical Flow Estimation
In this paper, we present a new method for the segmentation of moving objects. We use one of the most powerful variational method for computing the optical flow and we exploit this information in the segmentation. This segmentation lies on well-known techniques of active contours. Since we can distinguish moving objects from static elements of a scene by analyzing norm of the optical flow vecto...
