A Lossy Coding Scheme for Images by Using Daubechies Wavelet Transform s and 2 - D Entire Cross - point Regions

摘要: This p aper presents l os sy coding scheme for images by u sing the Daubechies w avelet t ransform s D4 (DWT - D4) and he heory of c ross point r egions with 2D E ntire C R ( DECR ) . The base this statement is effect Gray on cross which are neighbor to poi nts grey levels 2 n matrix coefficients wavelet b efore an adjacent data set , very convenient quantization then we can determine entire region CR). After codin g these regions always contain bits 1 or 0 much more than another depending number each bit plane after
