Method for encoding and decoding motion model parameter, and method and apparatus for video encoding and decoding using motion model parameter

摘要

method for using the temporal correlation between the image frames and transmitting the motion model parameters to efficiently move image encoding method and apparatus using the model parameters , the decoding method and apparatus are disclosed . According to the present invention in consideration of the temporal correlation of motion vectors of representative points representing the motion model parameters and encoding the motion model parameters , and by performing the global motion compensation for a previous reference image frame using a motion model parameters a plurality of generating a conversion reference picture and is characterized in that for coding the current image frame using them .
