The Motion Compensation technology allows faithful reproduction of a frame as close to the original. It eliminates image ghosts by automatically compensating for fast moving actions like car chases, horse racing etc. The results are equally good for both PAL & NTSC signals.
The process of improving video quality by smoothing and accurately compensating for the fine movement limitations that compression algorithms have.
Scheme of video signal processing (e. g. standards conversion), involving the use of Motion Vector s to skew the filtering axis (for example the interpolation axis) by correspondingly shifting parts of the source TV fields.
A decoding technique and advanced video acceleration function found on some display chips that speed up DVD playback by transferring the decoding process onto the card itself.
Both H.261 and MPEG-1 encoders can perform interframe compression by encoding the differences between the values in a macroblock in the picture being encoded and the values in the corresponding macroblock in the preceding image. Sometimes, however, it's desirable to encode the differences between the values in a macroblock in the current image and the values in a macroblock in the preceding image that is slightly offset from the one that corresponds spatially with the macroblock being encoded. This approach is desirable because it enables the encoder to track the movement of objects from image to image and, thus, to encode smaller differences. If an encoder uses this approach, it must of course record the extent of the offset mentioned above. This offset is recorded in a motion vector.
A step in the MPEG-2 video decompression (decoding) process. MPEG-2 A digital video and audio compression (encoding) technique defined by the Moving Pictures Expert Group (MPEG).
A step in the MPEG-2 video decompression (decoding) process. MPEG-2 A mathematical technique for compressing video data to reduce the data file size.
In video decoding, the application of motion vectors to already-decoded blocks to construct a new picture.
A video compression technique that makes use of the redundancy between adjacent frames of motion video.
The use of motion vectors to improve the efficiency of the prediction of pel values. The prediction uses motion vectors to provide offsets into the past and/or future reference pictures containing previously decoded pel values that are used to form the prediction error signal.
In video compression, Motion compensation describes a picture in terms of where each section of that picture came from, in a previous picture. This is often employed in video compression. It can be also used for deinterlacing.
