“…In this case, the PSNR of the synthesized view (PCC=0.4489) has a significantly lower correlation than the average PSNR of the decoded and synthesized views (PCC=0.8502) or the PSNR of the decoded view (PCC=0.9216).

When a stereo pair is formed from a decoded view and a synthesized view, it is unclear how the overall quality of the stereo pair should be assessed through objective quality metrics. In this paper, this problem is addressed considering a 3D video represented in the format of multiview video plus depth. The performance of different PSNR-based metrics are analyzed in terms of correlation with subjective perception of video quality. A set of subjective data collected through formal subjective evaluation tests is used as benchmark. Results show that, among the considered metrics, the PSNR of the decoded view has the highest correlation with the perceived quality while the PSNR of the synthesized view has the lowest correlation.Index Terms-3D, quality assessment, quality metric, asymmetric stereo, view synthesis.

“…Stelmach et al [1] have shown that for stereo pairs composed of an original view and a low pass filtered view, the perceived quality is closer to that of the original view. A similar behavior has been reported for pairs formed from an original view and a horizontally downsampled view.…”

“…The binocular suppression theory of the human visual system (HVS) is widely accepted, which assumes that the perceived 3D quality is constructed by the domination of the higher quality view [2][3][4][5][6]. The theory can be exploited in stereo video encoding to reach the best stereo rate-visual distortion (RD) performance.…”

“…Stelmach et al [3] first started to study the ways of asymmetric coding and the quality assessment thereof. In [4], they compared low-pass filtering with discrete cosine transform (DCT)-based quantization and reported that in a low-pass filtering experiment, the mean quality scores were close to the individual scores of the unfiltered reference view. On the other hand, in a quantization experiment, the image quality scores turned out to be an approximate average of the individual scores of the reference and auxiliary views.…”

Abstract:In 3D perception, the binocular suppression of the human vision, perceiving high quality 3D video in the case of a view in higher quality, can be exploited in asymmetric stereo video coding for efficient 3D rate scaling. Hence, the best stereo rate-visual distortion performance may be gained by asymmetric coding, which is the reduction of the spatial and/or quantization resolution of the low-quality view, while keeping the high-quality view in full resolution.However, how to determine the level of asymmetry and what type of scaling should be chosen are still in question. In this work, we try to assess the overall performance of the scalability options with several test contents. The test videos are encoded at critical bitrates with symmetric options and spatial or signal-to-noise ratio (SNR) asymmetric coding, and are subjectively evaluated in a stereo-polarized projection 3D display system. Two different types of evaluation methodologies are used: the Double-Stimulus Continuous-Quality Scale (DSCQS) and Subjective Evaluation of Stereo Video Quality (SESVIQ). Dense visual tests show that the spatial scaling is generally inferior when compared to SNR scaling, except that high motion scenes and symmetric SNR are more preferable for a higher bitrate. The characteristics of the video content should be taken into consideration for efficient stereo rate scaling.

“…Most compression schemes worked on the data present in the image in the form of repetitions. For example, alphanumeric characters are normally represented by a 7-bit ASCII code, but when we apply a compression process then only 3-bit code is required to represent the eight most common letters [5]. Here the main concept is to replace a particular thing in the image which repeatedly occurs with the number of its appearances.…”
