Motion compensation in computing is an algorithmic technique used to predict a frame in a video given the previous and/or future frames by accounting for motion of the camera and/or objects in the video. It is employed in the encoding of video data for video compression, for example in the generation of MPEG-2 files.
In computer vision and image processing, motion estimation is the process of determining motion vectors that describe the transformation from one 2D image to another; usually from adjacent frames in a video sequence. It is an ill-posed problem as the motion happens in three dimensions (3D) but the images are a projection of the 3D scene onto a ...
Intra-frame coding is a data compression technique used within a video frame, enabling smaller file sizes and lower bitrates, with little or no loss in quality. Since neighboring pixels within an image are often very similar, rather than storing each pixel independently, the frame image is divided into blocks and the typically minor difference between each pixel can be encoded using fewer bits.
Stock market prediction. Stock market prediction is the act of trying to determine the future value of a company stock or other financial instrument traded on an exchange. The successful prediction of a stock's future price could yield significant profit. The efficient market hypothesis suggests that stock prices reflect all currently available ...

The planar prediction mode in HEVC supports all block sizes defined in HEVC while the planar prediction mode in H.264/MPEG-4 AVC is limited to a block size of 16×16 pixels. The intra prediction modes use data from neighboring prediction blocks that have been previously decoded from within the same picture. Motion compensation
Obviously, these investments carry a hefty price tag. But all things considered, neither of them even puts a dent in Amazon's staggering cash pile, which currently sits at roughly $85 billion.
Description Pixel-prediction.svg. English: Three neighboring samples around the sample to be predicted. PNG's filter can use the data in pixels A, B, and C to predict the value for X. Pixels that have already been processed are marked in grey, the pixel currently being processed (X) is marked in cyan. Deutsch: PNG kann die Daten der drei ...
