DCT and Image Compression In the JPEG image compression algorithm, the input image is divided into 8-by-8 or 16-by-16 blocks, and the two-dimensional DCT is computed for each block. The DCT coefficients are then quantized, coded, and transmitted. The JPEG receiver (or JPEG file reader) decodes the quantized DCT coefficients, computes the inverse two-dimensional DCT of each block, and then puts the blocks back together into a single image. For typical images, many of the DCT coefficients have values close to zero these coefficients can be discarded without seriously affecting the quality of the reconstructed image. The example code below computes the two-dimensional DCT of 8-by-8 blocks in the input image, discards (sets to zero) all but 10 of the 64 DCT coefficients in each block, and then reconstructs the image using the two-dimensional inverse DCT of each block. The transform matrix computation method is used.

可以实现十进制转换成任意字长的二进制。并又可以按照这个二进制转换成十进制。这个程序对于分析不同字长对于IIR数字滤波器和FIR滤波器的影响是非常有用的。(Decimal to convert any word length of the binary. And also in accordance with this binary to decimal conversion. This program is very useful for the analysis of the impact of different word length for the IIR digital filter and FIR filter.)
