Noise Level Estimation for Natural Images Based on Scale-Invariant Kurtosis and Piecewise Stationarity
Noise level estimation is crucial in many image processing applications, such as blind image denoising. In this paper, we propose a novel noise level estimation approach for natural images by jointly exploiting the piecewise stationarity and a regular property of the kurtosis in bandpass domains. We...
