Before explaining the discrete cosine transformation function, we must know a few basics. It is a fact that image transformation involves the use of coefficients. In a DCT process, the coefficients have information regarding the image pixels. Very few coefficients carry a lot of information. While...

In another implementation, a function of the complete window, typically the square root of each pixel of the window, is applied to the blocks prior to processing and the remainder applied after processing. This softens tile edges going into the image processing application to permit better results...

The model of the degradation, i, is simple and has been studied by many researchers; the original data, o, have been smoothed or blurred by a degradation function, h, and a random noise, n, has been added. Unitary transforms play an important role in signal and image processing and ...
