摘要
TV模型是图像去噪中保持图像边缘的模型之一.运用L2-模型从观察图像中提取光滑的草图,然后利用TV模型从残余图像中恢复一些丢失的有用信息,从而有效地避免TV模型的阶梯效应,使得恢复后的图像具有很好的视觉效果.
TV model is one of the models with the quality of preserving edges in image denoising.In order to avoid the staircasing effect from the TV model,and make the restored image have a better visualization,the L^2-model is used to extract a smooth primal sketch from the observed image and then to obtain other meaningful signal by the TV model from the removed noise image.
