| Abstract: | A general framework of reconstructing a super-resolution image is proposed in this paper. Under the some restriction condition of degradation image uncertainty and complexity, we discuss the least mean square regulation reconstruction method of low resolution images which result from various factors except motion, and farther present an improved recursive steepest-descend iteration algorithm to realize the super-resolution reconstruction of more than one low resolution frame. Experimental results illustrate that this method can improve image reconstructing quality. |
