dct image compression
A discrete cosine transform (DCT) expresses a finite sequence of data points in terms of a sum of cosine functions oscillating at different frequencies. DCTs are important to numerous applications in science and engineering, from lossy compression of audi,Image Compression and the Discrete Cosine Transform ... Abstract. The mathematical equations of the DCT and its uses with image compression are explained.
