摘 要
研究了一类具有“突出”部分,如十字交叉,且带有椒盐噪声的模糊降质图像。在吸取了鲁棒性去椒盐噪声及p(x) 调和映照保持边界轮廓的优势上,建立了一个变分模型,然后利用负梯度流方法进行迭代。实验结果表明,该方法较好地保持了原图像的轮廓。

Abstract
In this paper, we study a class of degraded images with salt & pepper noise and stick shape, such as crossing. Combining the advantages of wiping off salt & pepper noise by robust method with protecting edge by p(x) harmonic map, we establish a variational model, and then iterative an evolvement equation by the steepest descent to conduct experiments. From simulation results, our method preferably keeps the edge of original image.
