In order to improve the quality of blind image restoration, quantum bit code algorithm is proposed. Quantum clone is selected in immune system, and antibody controlled. Antibody is determined value in state of linear superposition at random, state of quantum is observed and obtained by binary. Blind image restoration model is built, quantum code convolution is filled void pixel. Finally, process is given. Simulation shows that blind image restoration reconstruction of this algorithm is clear and better, local manimum error (LME) is least, structural similarity (SSIM) is closed to 1.
