What is Weak-Texture Image Noise Estimation about?

The paper proposes a novel noise level estimation method for weak-texture image patches using image power spectrum sparsity, which enhances the accuracy of noise estimation while reducing computational time compared to conventional methods. The approach involves selecting weak-texture patches based on power spectrum sparsity and estimating noise variance from these patches. Experimental results demonstrate the effectiveness of the proposed method across various images, particularly those with rich textures.
