Abstract :
A specified histogram constraint (SHC) algorithm is applied to the problem of restoration and reconstruction from one-bit phase information (OBPI). Experimental results show that the SHC algorithm can improve the convergence speed and the quality of reconstructed images. Because of the statistical distribution of an image´s histogram, an adaptive SHC algorithm is presented for the problem of image reconstruction from OBPI. Experimental results show its advantages over the SHC algorithm
