Signal and image restoration using shock filters and anisotropic diffusion
The authors define a new class of filters for noise elimination and edge enhancement by using shock filters and anisotropic diffusion. Some nonlinear partial differential equations used as models f...
Dense Disparity Map Estimation Respecting Image Discontinuities: A PDE and Scale-Space BasedApproach
TLDR
We present an energy based approach to estimate a dense disparity map from a set of two weakly calibrated stereoscopic images while preserving its discontinuities resulting from image boundaries. Expand
A Morphological Approach to Curvature-Based Evolution of Curves and Surfaces
TLDR
We introduce new results connecting differential and morphological operators that provide a formal and theoretically grounded approach for stable and fast contour evolution. Expand
Reliable Estimation of Dense Optical Flow Fields with Large Displacements
TLDR
In this paper we show that a classic optical flow technique by Nagel and Enkelmann (1986, IEEE Trans. Vision, Vol. 8, pp. 565–593) can be regarded as an early anisotropic diffusion method with a diffusion tensor. Expand
Automatic Lens Distortion Correction Using One-Parameter Division Models
TLDR
We present a method to automatically correct the radial distortion caused by wide-angle lenses using the distorted lines generated by the projection of 3D straight lines onto the image. Expand
Symmetrical Dense Optical Flow Estimation with Occlusions Detection
TLDR
We present a method to recover a dense optical flow field map from two images, while explicitely taking into account the symmetry across the images as well as possible occlusions and discontinuities in the flow field. Expand
An Iterative Optimization Algorithm for Lens Distortion Correction Using Two-Parameter Models
TLDR
We present an algorithm to automatically estimate two-parameter radial polynomial and division distortion models in images using the Hough transform enriched with a radial distortion parameter. Expand
An Algebraic Approach to Lens Distortion by Line Rectification
TLDR
We propose an algebraic approach to the estimation of the lens distortion parameters based on the rectification of lines in the image. Expand
Symmetrical Dense Optical Flow Estimation with Occlusions Detection
TLDR
We present a method to recover a dense optical flow field map from two images, while explicitely taking into account the symmetry across the images as well as possible occlusions in the flow field. Expand
Morphological snakes
We introduce a morphological approach to curve evolution. The differential operators used in the standard PDE snake models can be approached using morphological operations on a binary level set. ByExpand
