保真率 meaning in Chinese

fidelity factor

Taking the storage and transfer of mass image data into consideration , not only could favorable image compression techniques achieve high compression ratio and fidelity , they should also meet the demands of web applications , image compression need further detailed study , thus having developed into a specialized research field known as image coding
出于图像存储技术和图像通信的考虑,良好的图像压缩技术不仅能够实现高压缩率和高保真率,还能满足诸如渐进传输、图像渐现等网络应用的需要。因此,为了满足实际应用的需要,有必要对图像数据压缩处理进行深入细致的研究,目前已发展成为专门的研究领域:图像编码。
