| 英文摘要 | A new coding and rate control method for JPEG2000 is proposed to improve its coding efficiency. Through modifying the coding order, the most important passes are coded first in a whole tile. Then, a simple data-stream truncation method is able to both terminate the coding in advance and approximate the optimal rate distortion. At the end, a feasible parallel implementation is proposed and it is to speed up JPEG2000 significantly. The improved algorithm makes JPEG2000 much more beneficial to applications with the restricted computing resource on board. The research satisfies the elementary requirements of image compression of Space Solar Telescope. |
