The red channel of the compressed image. The number of bits needed to store the original each of the red, green, and blue channels is 512*768*8 = 3,145,728 for a total of 3,145,728 * 3 = 9,437,184 bits. This compressed version is stored in YCbCr space using 1,497,748 bits with 586,509 bits needed for the Y channel, 459,064 bits needed for the Cb channel, and 452,175 needed for the Cr channel. The compression rate for this image is about 1.27bpp! |
