Intra prediction is an effective method for reducing the coded information of an image or an intra frame within a video sequence. The conventional method today is to create a sample predictor block by extrapolating the reconstructed pixels surrounding the target block to be coded. The sample predictor block is subtracted from the target block and the(More)
Intra prediction is an effective tool for coding still images and intra pictures in video. The H.264/AVC video compression standard uses extrapolation of the reconstructed pixels surrounding the target block to be coded to form the sample predictor block. Our previous paper augmented this conventional intra prediction method with sample predictor blocks(More)
A new algorithm is proposed for predicting pixels for inter frame coding without side information. There are many approaches in the past that exploited either spatial or temporal correlations for generating prediction signals of an image in a block-by-block basis. Our method proposed in this paper exploits both spatial and temporal correlations at once to(More)
A template matching prediction based on a group of reconstructed pixels surrounding a target block enables prediction of pixels in the target block without motion information. The predictor of a target block is produced by minimizing the matching error of the template. Due to the freedom possessed by the template, the residuals of a target block may become(More)
A template matching prediction based on a group of reconstructed pixels surrounding a target block enables prediction of pixels in the target block without motion information. In this method, the predictor of a target block is produced by minimizing the matching error of the template. If the template contains features such as complex texture, an appropriate(More)
We consider the mobile service scenario where video programming is broadcast to low-resolution wireless terminals. In such a scenario, broadcasters utilize simultaneous data services and bi-directional communications capabilities of the terminals in order to offer substantially enriched viewing experiences to users by allowing user participation and user(More)
Video coding schemes, equipped with various kinds of prediction modes, improve coding efficiency by offering efficient prediction modes that adapt to the motion in a macroblock (MB). Operation time for motion estimation and mode selection, on the other hand, increases with the number of prediction modes. We have proposed a motion compensated prediction(More)
