基于TV模型和L 2模型的图像去噪方案

摘要

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 visualiza-tion,the L2-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.%TV模型是图像去噪中保持图像边缘的模型之一。运用L 2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。
