Finding sparse solutions to underdetermined inverse problems is a fundamental challenge encountered in a wide ra nge of signal processing applications, from signal acquisitio n to source separation. Recent theoretical advances in our understand ing of this problem have further increased interest in their application to various domains. In many areas, such as for example medica l imaging or geophysical data acquisition, it is necessary tofind sparse solutions to very large underdetermined… CONTINUE READING
