Visual sensor image enhancement based on non-sub-sampled shearlet transform and phase stretch transform
Abstract Acquiring clear images is a requisite in visual sensor networks. Image enhancement is an effective way to improve image quality. In this paper, non-sub-sampled shearlet transform (NSST) multi-scale analysis is combined with phase stretch transform (PST) to nonlinearly enhance the images cap...
