| 摘 要： | 将对数图像处理数学模型应用到图像还原中,采用全变分的方法获得了去除图像乘性噪声的新模型.该模型弥补了现有图像去噪方法的不足,很好地保持了图像的边缘细节特征,并具有与人眼视觉特征相吻合的特点.仿真实验结果表明,与现有的去噪方法相比,新模型很大程度上减小了图像在去噪处理迭代过程中产生的误差,不仅去噪效果更好,而且能很好地保...

| Abstract: | The logarithmic image processing(LIP) mathematic model is applied to image restoration in this article.For deleting image multiplicative noise,a new model is obtained by total variation.This model can remove effectively multiplicative noise and keep nicely the edge vein characteristic,it also has the feature being identical with human visual charecteristics.The simulation experimental results show that compared with current denoise methods,the new model is able to decrease the error in image denoise process... |
