Noise Estimation for Image Sensor Based on Local Entropy and Median Absolute Deviation

Noise Estimation for Image Sensor Based on Local Entropy and Median Absolute Deviation

Noise estimation for image sensor is a key technique in many image pre-processing applications such as blind de-noising. The existing noise estimation methods for additive white Gaussian noise (AWGN) and Poisson-Gaussian noise (PGN) may underestimate or overestimate the noise level in the situation...
