WebSep 20, 2024 · Dictionary learning based image compression has attracted a lot of research efforts due to the inherent sparsity of image contents. Most algorithms in the literature, however, suffer from two drawbacks. First, the atoms selected for image patch reconstruction scatter over the entire dictionary, which leads to a high coding cost. … WebSep 8, 2024 · Dictionary Learning (DL) is a long-standing popular topic for image representation due to its great success to image restoration, de-noising and classification, etc. However, existing DL algorithms usually represent data by a single-layer framework, so they usually fail to obtain the deep representations with more useful and valuable hidden …
