STUDIES ON SUB-IMAGE INFORMATION IN FINGER PRINT IMAGE COMPRESSION USING WAVELET DECOMPOSITION
指纹图象小波压缩中子图信息的研究

Sub-image information of the wavelet decomposed finger print image is essential to the quality of reconstructed image. This paper describes the importance of the sub-images according to the features of ringer print images, and provides a new method that can be used to compress texture images. It can simplify and accelerate the algorithm with a better reconstructed image quality as well as a larger compress ratio.
