Detailed profile of the context formation process in EBCOT is analyzed to get an insight into the characteristics of the operation. Column-based operation is adopted to enable higher process speed. Two speed-up methods, referred to as Pixel Skipping (PS), and Group-Of-Column Skipping (GOCS), are proposed. It is shown that over 60% of processing time can be reduced by exploiting the two methods. A column-based architecture using these combined speed-up ideas is then proposed. © 2001 IEEE. |
