摘　　要：图像锐化将模糊的图像变得清晰,图像边缘变得连续,线条纹理增强。锐化的图像易于计算机识别其纹理和颜色,并能准确地提取目标物体的边界。主要研究了图像增强技术中空域图像锐化的四种算法及其优缺点评估分析,并用其对麦积山文物图像进行锐化处理,同时,对每种处理结果作了合理的分析。研究认为,Laplacian算子能有效地修复麦积山文物图像轮廓和细节,并增强图像的对比度和清晰度,修复后的文物图像为进一步修复打下了理论基础。Image sharpening is to make the blurry image clear,enhance the edge of the image,so that the edge of the target object becomes distinct and the computer can extract the boundary of the target object.This paper mainly studies four algorithms of spatial image sharpening in image enhancement technologyand the realization of Matlab,analyzes and compares the advantages and disadvantages of each image processing method,and further gives a reasonable analysis of each result,and obtains an effective spatial sharpening technology.
