Abstract:

Considering the disadvantages of consuming too much time by the bit-plane scanning by EBCOT(Em-bedded Block Coding With Optimized Truncation)encoder of JPEG2000,a fast algorithm of bit-plane scanning isproposed for the progressive transmission of gray medical images based on the characteristics of the three··pass scan-ning.The algorithm generates the iun length query table of column skipping sign in the first pass,thus overcoming the shortcoming of the Group-of-Column Skipping method and realizing the jumping of any length column group.Experimental results show that,compared with the Group-of-Column Skipping method,the proposed method is of higher scanning efficiency,and the time consumption reduces to 94%of that of the Group-of-Column Skipping method.

Key words: bit-plane, fast scanning, gray medical image；three-pass scanning, Group-of-Column Skipping, iun length table
