Retinex algorithms for image enhancement. They are specially useful to process images with uneven illumination.
Still a work in progress. Next, I want to implement other techniques for color correction.
You may use pip to install retinex.
pip install retinexHere is an example of how to use MSRCR (multi-scale retinex with color correction).
import skimage
from retinex import msrcr
img_original = skimage.io.imread("leaves.jpg")
img_msrcr = msrcr(img, sigmas=(25., 50., 100.,))
Check the examples folder for some more samples:
Images in the sample_images folder were made freely available online by talented photographers. My big thanks to them:
