基于能量分布的自适应整体变分去噪方法

An adapted denoising model of total variation based on energy distribution

摘要: 研究了整体变分去噪的机制,提出了一种基于能量分布的自适应整体变分去噪模型,该模型继承了传统整体变分去噪保边缘的优点,并能够根据图像区域能量分布的特征,在不同区域自适应地选择相应的规整化参数,进行不同强度的去噪,在去噪保边缘的同时,较好地保持了纹理细节,在一定程度上克服了传统整体变分方法的缺点.

Abstract: By studing denoising mechanism of ROF TV model,an adapted TV model based on the energy distribution is proposed.This model inherited the merit of ROF TV model in denoising and keeping edge.It can chooses the regulating parameter in the different region according to region energy distribution in the image,and denoise by this parameter.So it can hold the edge and texture while denoisng.This method overcomed the shortcoming of ROF model in some degree.
