摘　　要：在对JPEG 2000标准的基本原理、编码流程所使用的算法等进行了详细分析的基础上,研究了决定编码器性能的核心算法;对JPEG 2000中EBCOT算法的位平面编码进行了两点改进,并将改进后的算法在DSP硬件平台上得以实现。实验结果表明改进后的算法具有良好的压缩性能。In this paper, on the basis of analyzing the basic theory of JPEG2000 and its encoding process, it studied core algorithm of JPEG2000 that determined the performance of the encoder. According to the bit plane coding of JPEG2000,the paper induced two improvement methods and realized the improved algorithm on the hardware platform of DSP. Experimental result shows that the improved algorithm has well performance of compression.
