JPEG2000的技术特点及应用分析JPEG2000 codec for robust, scalable pro and consumer video The JPEG2000 wavelet-based algorithm generates a compressed codestream that retains the ability to easily extract different representations of the image, including different frame dimensions, without transcoding or recompressing. By Yuzo Shida Analog Devices, Wilmington, MA Digital imaging of still images and video has become widespread in consumer, industrial, military, and scientific markets in large part because of compression -shrinking the original image file to a fraction of its original size by reducing redundancy within the image. The compressed file not only consumes significantly less memory space, but it now can be easily transmitted electronically over transmission media with limited bandwidth. All compression algorith……
