Ill-posed inverse problem is commonly existed in signal processing such as image reconstruction from projection, parameter estimation on electromagnetic field, and path optimization in IP network. Usually, the solution of an inverse problem is unstable, not unique or does not exit. Traditional approach to solve this problem is to estimate the solution by optimizing a regularized objective function. In some cases, recovery of visual features is most emphasized in that solution; thereof thedoi:10.4304/jmm.5.3.240-247 fatcat:zdpnle2ijrgpzglm6k3uszitwq
