Matrix projection and its application in image processing

Abstract

This paper proposes a new projection-based image compression and decompression (PC-PD) method for image processing. Inspired by Cheng projection processing vector, a novel matrix projection is introduced based on the matrix space structure and topological structure. Building on the matrix projection, the PC-PD method is developed to handle images. The effectiveness of the proposed method is demonstrated through experiments on gray and color images, as well as comparisons with other compressed sensing (CS) methods.
