Images processed via four prediction methods. (a) Image that has been processed by the traditional discrete cosine transform-based image denoising method. (b) Image that has been processed by the GM(1,1). (c) Image that has been processed by the HDGM(1,1). (d) Image that has been processed by the NDGMp/q(1,1).
