Abstract in different language:	This paper presents the color-dependent method of removing inter-view redundancy from multiview video. The pruning of input views decides which fragments of views are redundant, i.e., do not provide new information about the three-dimensional scene, as these fragments were already visible from different views. The proposed modification of the pruning uses both color and depth and utilizes the adaptive pruning threshold which increases the robustness against the noisy input. As performed experiments have shown, the proposal provides significant improvement in the quality of encoded multiview videos and decreases erroneous areas in the decoded video caused by different camera characteristics, specular surfaces, and mirror-like reflections. The pruning method proposed by the authors of this paper was evaluated by experts of the ISO/IEC JTC1/SC29/WG 11 MPEG and included by them in the Test Model of MPEG Immersive Video.
