Method and apparatus for coding moving image and medium for recording program of coding moving image
Hudson Soft Co., Ltd., , JP;
Abstract
A method and an apparatus for coding a moving image, capable of obtaining high image quality and high rate of data compression, are provided. The method compares a pixel block of current image to be coded and a pixel block of preceding image within a predetermined region of preceding frame, one after another. The method seeks a specific preceding-image pixel block minimizing matching error. If the matching error relative to the specific preceding-image pixel block exceeds an acceptable value, than the method obtains one or more of orthogonal base systems for approximating AC component vector in the current-image pixel block by inter-frame adaptive orthogonal transformation having, as nest thereof, preceding image data within a predetermined region including the specific preceding-image pixel block. The method thereby codes the moving image data.
