Sevket Derin Babacan: Noise estimation for images. Google, IP Spring, February 10, 2015: US08953877 (2 worldwide citation)

Implementations relate to estimating noise in images. In some implementations, a method includes extracting a plurality of sample blocks of pixels from a received image, where each sample block includes a subset of pixels of the image. One or more of the sample blocks are examined for texture conten ...
