Abstract
An algorithm for decreasing the effect of film-grain noise in image compres sion is proposed. The algorithm operates. in the transform domain in conjun ction with quantisation. Although any orthogonal transforms suitable for th is application, the orthogonal wavelet transform is preferred due to the si mplicity in calculating the filter coefficients.
