In order to combine a sequence of low-resolution noisy blurred images to produce a higher resolution image,a method of super-resolution image reconstruction is presented based on P-M(Perna-Malik) diffusion.We analyze the robust of lp norm.And,we present the algorithm to the super-resolution image reconstruction based on P-M diffusion,and a regulator called energy condensation integral is introduced to prevent the fattening of bright spots or linear structures.The simulation results confirm that the improvem...
