Encoding and decoding motion via image segmentation

摘要

A system and method for encoding and decoding a video image having a plurality of frames is disclosed. The method includes a previously reconstructed frame that is segmented to create an alternate reference frame used to encode a current frame. The segments of the previously reconstructed frame are assigned motion parameters, which are used to compile the alternate reference frame. The current frame is encoded and the segmentation parameters and motion parameters are transmitted in the bitstream. The segmentation parameters and motion parameters can be used by a decoder to recreate the alternate reference frame in order to decode the encoded current frame.

1. A method for encoding a current frame of a video signal having a plurality of frames, each frame having a plurality of pixels, the method comprising:
segmenting a previously reconstructed frame into a plurality of image segments using a segmentation parameter, at least one image segment from the plurality of image segments having a segment identifier; determining, using a processor, a motion parameter for each respective image segment from the plurality of image segments; creating an alternate reference frame from the previously reconstructed frame using the motion parameter for each respective image segment from the plurality of image segments; and encoding the current frame using the alternate reference frame for motion prediction.
