This algorithm changes the form of nonlinear filter, and denoises the image by combining with the method of total variation minimization. 该算法改变了原算法中非线性滤波的方式,并结合总变分最小化方法对图像进行降噪处理。
Based on the theory of total variation minimization and the active contour image segmentation method, we proposed a simple linear model of texture images which regards a texture image as a sum of a photo prototype image and a texture sub-image. 不同于传统的提取纹理特征量进行纹理分割的方法,本文将图像复原和重建中的总变分最小化方法和活动围道分割方法相结合,提出了一种简单的线性纹理模型。
