Efficient disparity map estimation of stereo images under varying radiometric factors

Stereomatching is the process of finding corresponding points of two images of the same scene. If the illumination conditions of the two images are non-uniform, undesirable result will be obtained. Homomorphic filtering can be used as a preprocessing step to reduce these illumination variations of the stereo images. Disparity map is calculated using block matching and dynamic programming techniques. A sequence images of the same scene is used for the purpose of matching.
