Using Global Motion Compensation for Efficient Video Coding
نویسنده
چکیده
A way of introducing compensation of camera caused global motion into MPEG-2 is described in this paper. A videocoding method is proposed where global motion estimation of four parameters regarding horizontal and vertical scrolling, zooming and rotation is performed and a global-motioncompensated image is produced for use as a reference frame for MPEG-2 coding. The experimental results have shown an improved performance over MPEG-2 on sequences with pronounced camera zoom and rotation.

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...

We present a new motion representation and estimation scheme that leads to improved coding eeciency of block-based video coders like e.g. H.263. The proposed scheme is based on motion-compensated prediction from more than one reference frame. The reference pictures are warped versions of the previously decoded frame. AAne motion parameters are used as warping parameters approximating the motion...

In this paper, we develop a hierarchical global motion estimation/compensation system which is used to improve the block-based motion compensation in the current low bitrate video coding standard H.263. The system first detects the background motion by examining the local motion information using hierarchical block matching and global motion estimation algorithm. If the background motion exists...
