| 摘 要： | 本文在Perona和Malik及Catte等前人的工作基础上提出了一种新的图像去噪模型，并做了数值仿真，实验结果证明该模型不但能有效地去除噪声，而且能增强边缘并保持边缘位置，使处理后的图像清晰度和对比度都有大大增加，看上去也比较真实自然．

| Abstract: | In this paper,on the basis of the previous work of Perona and Malik and Catte,etc.,we propose the modified model of image denoising,do the model's numerical simulation.The experimental results show that the model can not only remove the noise effectively,but also to enhance and maintain the edge,and make the processed image sharpness.And contrast are greatly increased,looks also more really and naturally. |
