This paper proposes an image sharpening method based on Laplasse algorithm, and the algorithm is implemented in DSP. The basic principle of the Laplasse operator image sharpening, Laplasse operator and derive the image sharpening. Secondly, according to the Laplasse operator, the CCS2 software using C language to compile the main function and the read image data Readimage The InitImage function sub function, initialization of image and image sharpening in the calculation of Laplace functions and other functions to achieve image algorithm based on Rui Huacheng Laplasse Sequence. Finally, using three pairs of fuzzy image authentication image sharpening effect. Comparison of the experimental results, we use the algorithm of image sharpening processing than the original image is clear.
