说明：  该文提出了一种基于拉普拉斯算法的图像锐化方法，并在DSP 上实现其算法。首先研究拉普拉斯算子锐化图像的基本原理， 并推导出图像锐化的拉普拉斯算子。其次，根据拉普拉斯算子，在CCS2 软件上运用C 语言编写主函数和读取图像数据的Readimage 子函数、初始化图像的InitImage 子函数和对图像锐化的计算Laplace 子函数等子函数来实现基于拉普拉斯算法的图像锐化程 序。最后采用三副模糊图像验证图像锐化的效果。比较实验结果，可知运用该算法锐化处理的图像比原来图像清晰。
(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.)
