This paper presents detailed analysis of the CABAC efficiency when operating in the HEVC in a number of bits per number of bins manner. The paper reveals what fraction of bit is produced by the CABAC for each and every binary symbols encoded in HEVC. The statistics of bins encoded with a given efficiency are presented for the three types of video data: 1) prediction error of image samples, 2) motion...
For the new HEVC compression technology, the analysis of accumulation of quality losses in multi-generation coding is still an open problem. In this paper, we describe the results of extensive experiments that demonstrate quality loss accumulation in 300 encoding-decoding cycles using the HEVC codec in the All Intra mode. For consecutive encoding cycles with constant encoder configuration, the coding...
The method presented in this paper uses motion information to complement the state-of-the-art depth estimation technique. The use of motion field correspondence between different views in the matching cost function for disparity computation is proposed. In addition, edges from motion maps are used to modify smoothing cost function in the algorithm in order to preserve sharp edges of moving objects...
The paper describes a technique for compression of a stereoscopic video pair together with the corresponding two depth maps. The proposed encoder produces a joint bit-stream for two viewpoint video sequences and two depth maps. Thus the headers with the control information is shared for all 4 video items. Moreover mutual correlation between these items is exploited by use of the multiview compression...
The paper deals with prospective 3D video transmission systems that would use compression of both multiview video and depth maps. The paper addresses the problem of quality of views synthesized from other views transmitted together with depth information. For the state-of-the-art depth map estimation and view synthesize techniques, the paper proves that AVC/SVC-based multiview video coding technique...
A new scintillating fiber detector has been built for the COMPASS experiment at CERN, in order to improve detection efficiency of high energy muons scattered at small angles with respect to the beam. We present the description of construction work, as well as performance study based on data collected during 2006 and 2007 data taking periods. Special attention is given to a new technology that we used...
