“…Most of the recently reported subjective assessments [5][6] [7] were carried out by encoding the video at various quantization parameters and varying the level of quantization until subjects perceive a difference. However, as described above, the video coding artifacts consists of two parts, blur- ring and blocking artifacts.…”

Abstract-It is well known that when the two eyes are provided with two views of different resolutions the overall perception is dominated by the high resolution view. This property, known as binocular suppression, is effectively used to reduce the bit rate required for stereoscopic video delivery, where one view of the stereo pair is encoded at a much lower quality than the other. There have been significant amount of effort in the recent past to measure the just noticeable level of asymmetry between the two views, where asymmetry is achieved by encoding views at two quantization levels. However, encoding artifacts introduce both blurring and blocking artifacts in to the stereo views, which are perceived differently by the human visual system. Therefore, in this paper, we design a set of psycho-physical experiments to measure the just noticeable level of asymmetric blur at various spatial frequencies, luminance contrasts and orientations. The subjective results suggest that humans could tolerate a significant amount of asymmetry introduced by blur, and the level of tolerance is independent of the spatial frequency or luminance contrast. Furthermore, the results of this paper illustrate that when asymmetry is introduced by unequal quantization, the just noticeable level of asymmetry is driven by the blocking artifacts. In general, stereoscopic asymmetry introduced by way of asymmetric blurring is preferred over asymmetric compression. It is expected that the subjective results of this paper will have important use cases in objective measurement of stereoscopic video quality and asymmetric compression and processing of stereoscopic video.

“…It has been known that human have a preference of one eye over the other and about 70% are right eyed, 20% left eyed, and 10% exhibit no eye preference. A recent study [11] found that the role of eye dominance have significant implications on the asymmetric view encoding of stereo views. These results suggest that the right-eye dominant population does not experience poor 3D perception in stereoscopic video with a relatively low quality left-eye view while right-eye view can provide sufficient good quality.…”

Abstract-Most of the TV manufacturers have released 3DTVs in the summer of 2010 using shutter-glasses technology. 3D video applications are becoming popular in our daily life, especially at home entertainment. Although more and more 3D movies are being made, 3D video contents are still not rich enough to satisfy the future 3D video market. There is a rising demand on new techniques for automatically converting 2D video content to stereoscopic 3D video displays. In this paper, an automatic monoscopic video to stereoscopic 3D video conversion scheme is presented using block-based depth from motion estimation and color segmentation for depth map enhancement. The color based region segmentation provides good region boundary information, which is used to fuse with block-based depth map for eliminating the staircase effect and assigning good depth value in each segmented region. The experimental results show that this scheme can achieve relatively high quality 3D stereoscopic video output.

“…Our work uses a similar approach but considers the human visual system as well as the autostereoscopic displays which do not require glasses for experiencing 3D video. Our work on the use of asymmetric view coding based on H.264 was reported in [5]. The key challenges in 3D TV development are presented in [6].…”

There is a renewed interest in the 3DTV research primarily due to the advances in low cost 3D display technologies. The two views required for 3DTV can be compressed using standard video compression techniques. MPEG-2 is widely used in digital TV applications today and H.264/MPEG-4 AVC is expected to be the leading video technology standard for digital video in the near future. The compression gains and quality of 3DTV will vary depending on the video coding standard used. While inter-view prediction will likely improve the compression efficiency, new approaches such as asymmetric view coding are necessary to greatly reduce bandwidth requirements for 3DTV. This demonstration will show the quality of 3D video experience on autostereoscopic displays using H.264 and MPEG-2. We will also show the benefits of using asymmetric view coding as well as the role of eye dominance on 3DTV experience.
