摘要
为提高激光医学图像的复原效果,提出一种改进全变差的激光医学图像复原方法。首先将原始激光医学图像划分成边缘区域和非边缘区域两部分,然后分别从中选择四邻域像素,并采用改进TV法对它们分别进行去噪处理,最后采用仿真实验对其性能进行分析。实验结果表明,本文方法较好地解决了传统TV法存在的缺陷,不仅能够保留激光医学图像边缘和细节信息,而且提高了激光医学图像信噪比,改善了激光医学图像的视觉效果。
In order to improve the recovery effect of laser medical image,a new restoration method of laser medical image based on improving total variation is proposed. First,original laser medical image are divided into edge region and non-edge region,and then,four neighborhood pixels are selected from different parts and the improved TV method is adopted to deal with them respectively,finally,the simulation experiment is used to analyze its performance. Experimental results show that the proposed method can solve the defects of the traditional TV method,which not only can preserve the edge and detail information of laser medical images,but also can improve the image signal to noise ratio and the visual effect.
