Abstract: Steganography aims to conceal secret data into common media, and steganalysis takes the adversarial position by trying to reveal embedding traces. Most of the existing steganographic schemes for spatial images are designed for gray-scale images.… read more here.

DOI: 10.3390/a15060176
Abstract: The group sparse representation (GSR) model combines local sparsity and nonlocal similarity in image processing, and achieves excellent results. However, the traditional GSR model and all subsequent improved GSR models convert the RGB space of… read more here.
