2D Discrete Cosine Transform

The program allows you to explore the two-dimensional discrete cosine transform (DCT) of images for different values ​​of the quantization coefficients. It is possible to estimate the peak signal-to-noise ratio and the entropy of the DCT coefficients. It is possible to copy the results to the clipboard. The program can be used to explore the digital image processing steps that are part of the JPEG algorithm. The results can be used in the preparation of diploma and laboratory work.
