Discrete cosine transform (DCT) is widely used transform in image processing, especially for compression. Some of the applications of two-dimensional
DCT involve still image compression and compression of individual video frames, while multidimensional DCT is mostly used for compression of video
streams and volume spaces. Transform is also useful for transferring multidimensional data to DCT frequency domain, where different operations, like
spread-spectrum data watermarking, can be performed in easier and more efficient manner. A countless number of papers discussing DCT algorithms
