Python bindings for Miguel Colom's implementation of the Ponomarenko et al. method.

Version 0.0.4 -- March 23, 2020

The C++ code used in this repository has been peer-reviewed as part of the IPOL publication:

Miguel Colom, and Antoni Buades, Analysis and Extension of the Ponomarenko et al. Method, Estimating a Noise Curve from a Single Image, Image Processing On Line, 3 (2013), pp. 173–197. https://doi.org/10.5201/ipol.2013.45

Run

pip install -e .

from the directory where setup.py is located.

from ponomarenko import estimate_noise

bins, noise_std = estimate_noise(image)

The method estimates the standard-deviation of the noise (in noise_std) in different intensity bins, which centers are given in the first output bins.
