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

基于ROF全变差分模型，用于图像去噪，并利用split bregman算法进行加速运算-ROF points based on total variation model for image denoising, and using split bregman accelerated computing algorithms
