Method and Device of Motion Estimation for Depth Video Coding by curved surface Modeling and NON-TRANSITORY COMPUTER READABLE RECORDING MEDIUM

摘要

An embodiment of the present invention comprises the steps of: dividing a current screen on an image plane on which an object on a camera coordinate system and a background is projected into a target block of size m * n (m, n is a positive integer); Selecting a reference block of size m * n by searching an area of i * j (i and j are m, n or more positive integers) of the reference screen on the image plane; Modeling each of the first curved surface in the target block and the second curved surface in the reference block to detect information of the first and second curved surfaces; Converting a second curved surface in the reference block based on the information of the first and second curved surfaces; Calculating a difference signal between the first curved surface and the converted second curved surface; And encoding at least one of the difference signal, the motion vector according to the displacement of the target block and the reference block, and the first and second curved surface information. Can provide.
