Image compression reduces time and cost in image storage without significant reduction of the image quality. This paper puts forward a wavelet-based predictive image coding algorithm, which has a higher coding rate than traditional coding algorithm. Based on the algorithm above, this article adopts the selective image compression technique to compress facial images. This algorithm attains a compression ratio from decade to several decades and settles the transmission and storage problem preferably.
