摘要
在图像处理时,常常需要对图像进行平滑,但是平滑后图像的轮廓往往变的有些模糊,为了改变这一影响,需要对图像进行锐化处理,使图像边缘信息呈现出来。对几种图像锐化的方法进行研究,并且对Sobel算法进行改进,进一步对各种方法进行Matlab仿真,分析它们的优缺点,为工程应用提供参考。
When we deal with the images,the images often need smoothing,but the contour of the smoothed image always become blurred.In order to change this influence,we need to sharpen the images,in order to show the edge information of the images.We studied several method of the image sharpening, at the same time,we improve the algorithm of the Sobel,simulationing these algorithm by Madab,analysis oftheir advantages and determination,provide a reference for engineering applications.
