| 摘 要： | JPEG2000是国际标准化组织指定的新一代静态图像压缩标准,支持感兴趣区域(ROI)编码是JPEG2000标准中的一个新特点.本文在分析了两种标准算法的优缺点之后,提出了一种新的ROI编码方法--混合编码方法,这种算法不仅可以灵活控制ROI区域和背景区域的画质,还可以有效编码多个具有不同优先级的ROI区域,而不需要编码形状信息.仿真结果证实了该算法的有效性.

| Abstract: | JPEG2000 is the latest static image compression standard developed by the ISO/ITU-T,Region of interest coding is of a new feature in JPEG2000.After analyzing the advantages and the weaknesses of the two standard ROI coding methods defined in JPEG2000,a new region of interest coding method called mixed coding method is proposed,it can control the quality between the ROI and the background flexibly,but also support multiple ROI coding in one image with different degrees of interest without coding shape inform... |
