sRGB gamma tranformations in C++ and Python

Correct Gamma in OpenCV

It is (as far as I know) not possible to resize, blur, or do any other arithmetic on images in OpenCV. This repository provides the missing code needed: transformations from sRGB to linear and back. This takes the gamma into account.

For an explanation and a lot more information about the problem, see

• What every coder should know about gamma
• Gamma error in picture scaling

Code is available in C++ and Python.

See the Python notebook for examples.
