Compressed sensing of astronomical images:orthogonal wavelets domains (1111.6276v3)
Published 27 Nov 2011 in cs.CV, astro-ph.IM, and physics.data-an
Abstract: A simple approach for orthogonal wavelets in compressed sensing (CS) applications is presented. We compare efficient algorithm for different orthogonal wavelet measurement matrices in CS for image processing from scanned photographic plates (SPP). Some important characteristics were obtained for astronomical image processing of SPP. The best orthogonal wavelet choice for measurement matrix construction in CS for image compression of images of SPP is given. The image quality measure for linear and nonlinear image compression method is defined.
