Furthermore, we demonstrate that it is not feasible to find a kernel matrix that precisely characterizes ... filter in terms of the DCT-KLD (Kullback-Leibler divergence of discrete cosine transform) ...

The discrete cosine transform, quantization, rounding, and truncation together form a transformation that (under the right conditions) leads to a predictable set of fixed points. Unlike watermarking, ...

In ordinary practice, we perform a spectral analysis on time-domain data. However, in step (6) above we are performing a discrete cosine transform on information that is already in the frequency ...

This repository contains a JPEG image encoder implemented in C. It takes a BMP image as input and encodes it using Discrete Cosine Transform (DCT), quantisation, and Run-Length Encoding (RLE), ...
