Motion compensation of motion vectors

چکیده
Motion compensation of image data has long been used for video compression. “Meta-motion” compensation, or motion compensation of motion vectors is presented as a new approach to data compression useful in very low bitrate (VLB) applications. Whereas present motion coding simply takes advantage of temporal redundancies among images, this new, computationally simple approach takes advantageof temporal redundanciesbetween subsequentvector fields to efficiently code motion. Taking advantage of both the temporal redundancy of motion vectors and the “mapping” property of motion vectors, this method is shown to decrease the bitrate for vector coding in sequences with complex motion.

New adaptive interpolation schemes for efficient meshbased motion estimation
Motion estimation and compensation is an essential part of existing video coding systems. The mesh-based motion estimation (MME) produces smoother motion field, better subjective quality (free from blocking artifacts), and higher peak signal-to-noise ratio (PSNR) in many cases, especially at low bitrate video communications, compared to the conventional block matching algorithm (BMA). Howev...

Increasing frame rates by frame interpolation is one of the main challenges in video processing. Motion estimation and motion compensation are two main keys of video frame interpolation algorithm. Motion estimation algorithms are used to get refine motion vectors while motion compensation algorithm assigns motion vectors accurately. Recent studies on video frame interpolation mainly focused on ...

In prior work, we developed a fast inverse motion compensation method that can be implemented directly on the DCT domain representation derived from the compressed bitstreams conforming to MPEG, H.261 and H.263 standards. That work was restricted to compressed-domain representations wherein the motion-vectors have integer pel accuracy. Here, we extend this work to sub-pel accurate motion-vector...
متن کاملA Novel Filter for Block-Based Object Motion Estimation
Noises, in the form of false motion vectors, cannot be avoided while capturing block motion vectors using blockbased motion estimation techniques. Similar noises are further introduced when the technique of global motion compensation is applied to obtain “true” object motion from video sequences, where both the camera and object motions are present. We observe that the performance of the mean a...
متن کاملLow-cost multi-hypothesis motion compensation for video coding
In conventional motion compensation, prediction block is related only with one motion vector for P frame. Multihypothesis motion compensation (MHMC) is proposed to improve the prediction performance of conventional motion compensation. However, multiple motion vectors have to be searched and coded for MHMC. In this paper, we propose a new low-cost multi-hypothesis motion compensation (LMHMC) sc...
