WebJan 21, 2024 · The only difference between the DCT and IDCT is where coefficient are taken into account. You should replace line 46 in your code by. sum = sum + ck*cl*dct1; where ck and cl are computed as in lines 24-34, but for k and l. And suppress ci*cj in line 49. BTW, this java code is exceptionally inefficient. WebThe DCT.java source code is also availible. The implementation is also handy for seeing how to break the image down, read in 8x8 blocks, and reconstruct it. The sample graphic …

Some colors are more sensitive to human eyes and thus are high-frequency colors. Some colors of chromium compounds like Cb and Cr are less sensitive to human eyes thus can be ignored. Then we reduce the size of pixels in downsampling.
