Colour Matching Between Stereo Pairs of Images
This paper outlines the process of colour matching stereo pairs of images using a disparity map as input along with the original images. We describe the functionality of a plugin developed for Nuke, which we call Eyematch, that performs this automatic colour matching under conditions set by the user. The user is presented with various parameters to fine tune the matching process, but no prior k...
متن کاملColour Contribution for Stereo Image Matching
We examine the contribution of colour for the computation of depth maps from a stereo pair of colour aerial images. As a matter of fact we propose an original method based on fusion theory to compute dense and reliable depth maps. The fusion is directly applied on correlation curves obtained for each colour channel. In order to evaluate the quality of the elevation map, we compare our results t...
متن کاملEnhancing the Volumetric Approach to Stereo Matching
This paper describes a volumetric stereo algorithm for obtaining disparity maps and identifying the presence of occlusions. It works in the (rows x columns x disparities range) space initializing the voxels with a measure of the similarity between the stereo pair they represent (Similarity Phase) and refining these values through an iterative process which inhibits all voxels but one placed alo...
متن کاملA colour correlation-based stereo matching based on 1D windows
In this paper, we propose an original approach to colour correlation-based stereo matching with mono-dimensional windows. The result of the algorithm is a quasi-dense disparity map associated with its confidence map. For each pixel, correlation indices are computed for several widths of windows and several positions of the current pixel. Three criteria, extracted from each correlation curve, ar...
متن کاملSpecularity Removal using Dark Channel Prior
The reflectance of inhomogeneous objects can be described as a linear combination of diffuse and specular reflection components. Most computer vision algorithms assume that visually observable surfaces consist only of diffuse reflection. The existence of specular reflection can be misleading to these computer vision algorithms. A new algorithm dark channel prior based specularity removal is pro...
