摘要
实际应用中,图像不仅需要改善反差而且还有噪声污染。针对传统方法对图像先后做反差增强和去噪所产生的不可避免的缺陷,提出一种基于PDE的改进的反差增强方法,算法将增强和去噪过程统一起来同步进行,并加入一个特殊调整项,进一步改善图像视觉效果。实验证明改进后的方法整体上比传统方法具有更好的性能,能够有效地避免传统方法的缺陷。
In practice,images often need not noly to improve the contrast but also to remove pollution.For the inevitable defects of the traditional approachs for image contrast enhancement and denoising,an improved contrast enhancement method based on partial differential equation is proposed,which combines the process of enhancement and denoising,and added a special adjustment to further improve the visual effect.Experimental results show that the improved method has better performance than the traditional approach.It effecttively avoid the shortcoming of traditional methods.
