Abstract In order to improve image reconstruction quality, quantum bit plane code algorithm is proposed.Firstly, image pixel gray was coded, and then intermediate segment gray level filter matrix was obtained. Secondly, quantum bit is transformed Walsh-Hadamard, input image pixel is decomposed low and high frequency part. Each positive and negative coefficient matrix was scanned,bit sign was inserted between positive and negative coefficient bit plane code stream. Finally the process is given. Simulation results show this algorithm reconstruction effect is clear, index of image signal to noise tate is largest and RMSE is close 0.
