| Abstract: | A great deal of medical images have been created by modern medical treatments, how to store, query and transmit these medical images have become a urgent problem. In this paper, the research on medical images based on integer to integer wavelet transform and embedded zerotree encoding is proposed. The scheme in this paper yields significantly better compression than the traditional JPEG standard, and it has the characteristic of embedded coding stream, which can meet the need of storage, query and transmission of medical images. |
