METHOD FOR ESTIMATING THE MOTION OF PICTURES USING 2-D TRIANGLE-PATCH WIRE FRAME MODEL

摘要

PURPOSE: A motion assumption method of a moving image using a two-dimensional triangle-patch wireframe model is provided to obtain a good image quality by removing discontinuity of images between blocks. CONSTITUTION: The current frame of input image signals are divided to N*N macro block units(200). Each divided macro block unit is bisected to triangle patches(202). the pixel value difference between the reference block with a determined range and a search block of the previous frame is calculated centered on each vertex of the triangle patch(204). A motion vector of the reference block of the current frame with minimum pixel value is obtained with the coordinate value of the matching block of the previous frame(206).
