图像在传输过程中，传递函数对高频成分有衰减作用，造成图像模糊，细节轮廓不清楚。图像锐化就是补偿图像的轮廓，增强图像的边缘及灰度跳变的部分，使图像变得清晰。亦分空域处理和频域处理两类[3]。-Image in the transmission process, the transfer function of the role of high frequency components are attenuated, resulting in image blurring, the details

多尺度Retinex代码算法，能够很好的是实现边缘锐化和对比度增强。-Multi scale Retinex code algorithm, can very good realize edge sharpening and contrast enhancement.

How to image processing using matlab: load image, BW, edge detection, noise remover, sharpening by any method by simple code (lp2m aray jakarta)

MATLAB实现图像去噪 滤波 锐化 边缘检测 源程序代码 有完美的代码和运行结果图-MATLAB for Image Restoration filter sharpening edge detection source code is a perfect code and run the results in Fig.
