![]() The result of a DCT is a transformation of the original source into the frequency domain. ![]() ![]() Now, I need to know how can I take advantage of this transformation? I'd like to detect other 8x8 blocks in the same image ( or another image ) that represent a good match.Īlso, What does this transformation give me? Why is the information stored in the top right of the converted image important? Into this an image with all the important information at the top right. ![]() Now I can transform an 8x8 section of a black and white image, such as: I based my algorithm on the ideas presented at the following URL: This technique is used in MPEG video encoding. I've implemented an image/video transformation technique called discrete cosine transform.
