Multiresolution discontinuity-preserving surface reconstruction
This paper proposes a single multiresolution framework for both surface "tting and discontinuities identi"cation in the surface reconstruction problem. In particular, the Mallat}Zhong wavelet transform modulus maxima (WTMM) representation is employed for representing the surface which allows the discontinuity detection and surface "tting to be carried out simultaneously in a cooperative manner ...
متن کاملOn Discontinuity-preserving Optic Flow
We investigate a modiication of Horn and Schunck's approach which leads to a better preservation of ow discontinuities. It replaces the quadratic smoothness term by a nonquadratic one. Energy minimization by steepest descent leads to a system of two nonlinear diiusion{reaction equations with a single common nonlinear diiusivity. This enables us to make use from techniques for nonlinear diiusion...
متن کاملHybrid stereo matching with a new relaxation scheme of preserving disparity discontinuity
A hybrid stereo matching algorithm using a combined edgeand region-based method is proposed to take the advantage of each technique, i.e. an exactly matched point and a full resolution disparity map. Region-based matching is typically more e$cient than edge-based matching, however, a region-based matcher lacks the capability of generating an accurate "ne resolution disparity map. The generation...
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 کاملImproved Edge Awareness in Discontinuity Preserving Smoothing
Discontinuity preserving smoothing is a fundamentally important procedure that is useful in a wide variety of image processing contexts. It is directly useful for noise reduction, and frequently used as an intermediate step in higher level algorithms. For example, it can be particularly useful in edge detection and segmentation. Three well known algorithms for discontinuity preserving smoothing...
