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.

说明：  这里有2组图，“1000.0.05”这一组是运行结果比较好的一组图，但是当时修改了时间间隔而没有改坐标说明，所以db1000.0.05.fig这幅图的坐标说明后来做了人工改正（应该是“time(0～250ms分成5000组,步长0.05ms”）。(Reuters, "1000.0.05" This group is running a relatively good results Reuters. But then amended the time interval and not changed coordinates Note So db1000.0.05.fig site map coordinates statement later became the artificial correction (should be "ti me (0 ~ 250ms group into 5000, 0.05 Step ").)
