Recently the interest in 3D video has significantly increased (as eg. could be seen on the consumer electronics show CES 2009). Because there is a lack of one clear recognized 3D standard, various different (proprietary or non-proprietary) standards or solutions are starting to enter the market already based on stereo where some kind of spatial sub-sampling is being applied. To avoid consumer confusion...
In this paper we analyze the substantial performance gap between distributed video coding (DVC) and well known state-of-the-art coders. We take a modular approach towards analyzing the performance loss in DVC and investigate 3 key components. These are quantization, bit stream generation and motion estimation. Their respective contributions to the total performance loss varies with the video properties...
The ongoing research in distributed video coding (DVC) for low complexity encoding is trying to shorten the substantial performance gap to well known state-of-the-art coders. One way of reducing this gap is to improve the quality of the motion compensated prediction. In this paper we investigate which motion estimation method to apply in DVC, comparing possible methods to produce a motion compensated...
After the introduction of HDTV, the next expected milestone is stereoscopic (3D) TV. This paper gives a summary of the new MPEG-C part 3 standard, capable of compressing the 2D+Z format, and shows how it can be used to serve the Is generation of 3DTVs. Furthermore it gives directions on how this standard could be extended to serve also the generations beyond.
Most existing feature-matching methods utilize texture correlation for feature matching, which is usually sensitive to contrast changes. This paper proposes a new feature-point matching algorithm that does not rely on the image texture. Instead, only the smoothness assumption, which states that the displacement field in a neighborhood is coherent (smooth), is used. In the proposed method, the collected...
Since the introduction of TV, major new steps have been color- and high definition (HD) TV. The next expected milestone is stereoscopic (3D) TV. Important ingredients are availability of suitable 3D displays, practical content generation and compression standards to carry the 3D signals.
The low bit rate of existing video encoders relies heavily on the accuracy of estimating actual motion in the input video sequence. In this paper, we propose a video stabilization and encoding (ViSE) system to achieve a higher coding efficiency through a preceding motion processing stage (to the compression), of which the stabilization part should compensate for vibrating camera motion. The improved...
