An Improved Image Denoising Model Based on Nonlocal Means Filter

Figure 2

Denoising of the images using three different methods. The images from top to bottom are 1.1.10, 1.1.11, 1.1.12 1.1.13, 1.3.01, and 1.5.03, respectively. The first column: the original images , the second column: noisy images with a white Gaussian noise (), respectively, the third column: denoised images by NLM, the forth column: denoised images by NLM2, and the fifth column: denoised images by INLM.
