Image VQ Coding Composed by essential Curved Surface units

Abstract

This paper realize a new coding in which images are constructed by a set of many kinds of unit curved surfaces using a vector quantization technique, and presents a design of vector quantization coding based on PQS(Picture Quality Scale) as a distortion measure. When we chose typical and essential curved surface units as initial codebook to construct an image, we have obtained a coding performance better than the performance in the case of splitting algorithm both in the case of open data and closed data. Our idea will develop into enhancement and modification of images. Furthermore we can expect the consideration of the structure of images and synthesis of images in this report will develop to Computer Graphics.
