基于小波变换的图像压缩算法

An image compression algorithm based on wavelet transform

介绍了小波图像压缩方法。图像经过小波基分解成低频部分和高频部分,根据人眼的视觉特征,把低频部分做编码处理,高频部分用阈值量化处理,对几种适合图像压缩的小波基经过试验比较出了压缩效果。

The wavelet image compression methods are introduced first.An image is decomposed to low and high frequency,and then the low frequency components are encoded while the high threshold quantified according human eye vision characteristics.The results of several wavelet transform for image compressing are shown here through the experiments.
