Image processing system using pixel-by-pixel motion estimation and frame decimation |
摘要 |
An image processing system for processing a video signal has an encoder and a corresponding decoder wherein the encoder includes a frame decimator; a current frame prediction block for estimating displacements between a previous and a current frames provided from the frame decimator, and providing a predicted current frame based on the displacements; and a subtractor for providing a difference between the predicted and the original current frames and providing motion vectors representing the displacement, and the decoder includes a current frame prediction block for estimating displacements between the previous and the current frames and compensating the previous frame with the displacements to reconstruct the predicted current frame; and an adder for adding the reconstructed predicted current frame with the difference, to thereby reconstruct the current frame.
