Depth Map Reconstruction Based on Features Formed by Descriptor of Stereo Color Pairs

Abstract: An approach to depth map reconstruction from stereo pairs of color images in visualization of three-dimensional objects is proposed and substantiated for the first time. The approach makes use of a novel local image descriptor based on visual primitives and relations between them, namely, cocolority, coplanarity, distance, and angle. The new approach is compared with other well-known descriptors, such as DAISY and SID. Numerical experiments and an analysis and physical interpretation of their results obtained in the case of actual radiometric differences in the exposition or illumination of stereo image pairs have shown that the new approach is superior to other existing descriptors.
