Enhancement of the Horn and Schunck Optic Flow Algorithm by Means of Median Filters
نویسندگان
چکیده
For optic ow computation the Horn and Schunck algorithm is one of the most used and powerful. Some drawbacks are, nevertheless, intrinsically related to the approach that it is used. A smoothness constraint is imposed to the ow eld in order to produce a solution. This constraint causes the estimated eld to be uncorrect where motion discontinuities are present. In this paper the weight of this smoothness constraint is reduced by using median lters. Motion boundaries result to be better preserved by the modiied algorithm. Results are presented and possible developments are proposed.

A Study on Robustness of Various Deformable Image Registration Algorithms on Image Reconstruction Using 4DCT Thoracic Images
Background: Medical image interpolation is recently introduced as a helpful tool to obtain further information via initial available images taken by tomography systems. To do this, deformable image registration algorithms are mainly utilized to perform image interpolation using tomography images.Materials and Methods: In this work, 4DCT thoracic images of five real patients provided by DI...
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 کاملAdaptive Line Enhancement Using a Parallel IIR Filter with A Step-By-step Algorithm
A step-by-step algorithm for enhancement of periodic signals that are highly corrupted by additive uncorrelated white gausian noise is proposed. In each adaptation step a new parallel second-order section is added to the previous filters. Every section has only one adjustable parameter, i.e., the center frequency of the self-tuning filter. The bandwidth and the convergence factor of each secti...
متن کاملImproved Adaptive Median Filter Algorithm for Removing Impulse Noise from Grayscale Images
Digital image is often degraded by many kinds of noise during the process of acquisition and transmission. To make subsequent processing more convenient, it is necessary to decrease the effect of noise. There are many kinds of noises in image, which mainly include salt and pepper noise and Gaussian noise. This paper focuses on median filters to remove the salt and pepper noise. After summarizin...
متن کاملImplementation of Differential Optical Flow Algorithms in Natural Rigid Video Motion
Computing the optical flow of a sequence of images still remains a challenge in low-level video processing. Till present, none of the existing techniques has sufficiently generated accurate and dense optical flow fields to robustly represent video motion. In this paper we implement the optical flow algorithms through different lengths of displacements that exist in video motion of natural objec...
