Decoding system and method for proper interpolation for motion compensation
TLDR
In this article, a motion compensation predictor is adapted to determine a likely local nature of a reference frame data area in the video data stream and then apply proper interpolation to the reference-frame data area according to the determined likelihood of local nature.Abstract:
The present invention can complement and benefit virtually any method utilizing motion compensation to decode an inputted digital video data stream by determining a likely local nature of reference frame data area in the video data stream and then applying proper interpolation to the reference frame data area according to the determined likely local nature of the reference frame data area. The present invention can also complement and benefit virtually any decoding system utilizing motion compensation to decode an inputted digital video data stream by providing a motion compensation predictor that is adapted to determine a likely local nature of a reference frame data area in the video data stream and then apply proper interpolation to the reference frame data area according to the determined likely local nature of the reference frame data area.read more

Image superresolution through edge extraction and contrast enhancement
TL;DR: In this article, a low-resolution bitmap is magnified to form a magnified image and edge detection is performed to find high contrast edges to produce a plurality of foreground and background decisions determining whether a portion of an image patch is a background or a foreground.

Method And Apparatus For Complexity Scalable Video Decoder
TL;DR: In this paper, a video decoding method, a video encoder and a video encoding method are described, which includes a motion vector resolution reducer (999) and a motion compensator (960) for decoding a video bitstream for an image block.
Patent
Reducing the resolution of media data
TL;DR: In this article, a method and system for reducing the resolution of media data is proposed, where input data at a first resolution are received from a source and the input data can be downsampled to generate compressed downampled data at reduced resolution.
Patent
Moving picture encoding method and motion picture decoding method
TL;DR: In this article, a motion picture encoding method where the encoding mode of a block to be encoded is determined, is judged whether or not it is possible to conduct a scaling if the determined encoding mode is a temporal direct mode, and motion compensation is carried out by using another encoding mode or by not conducting any scaling if it is judged to be impossible.
