Adaptive stripe based patch matching for depth estimation
A novel stereo matching technique for depth estimation in stereoscopic image pairs is presented. The input image pair is preprocessed in the intensity domain and together with edge maps an adaptive mesh in which individual elements approximate linearly modeled regions are obtained. Then, an iterative stripe based, quadrilateral patch matching technique is employed to estimate the depth map from the image pair in a hierarchical manner. Finally, the resultant map is postprocessed to smooth the depth map at the patch borders. The quality of the test results demonstrates the effectiveness of the technique.
