Multi-resolution encoding is an effective measure for medical image transmission and playback. After analyzing the wavelet transform iteration characteristic of two-dimension image, the paper presents a multi-resolution encoding algorithm for based on wavelet transforms, which can effectively use wavelet domain decomposition and rebuild iteration characteristic. Testing indicates that this method is easy to carry out, and has better compression effect.
