gray-world

A Python implementation of color constancy algorithms for photo enhancement, based on the comprehensive review by Foster (2011). This package implements several key color constancy techniques including Gray World assumption, White Patch correction, Von Kries adaptation, Retinex enhancement, and spatial color correction methods.

Do superpixels survive a lighting change? Benchmarking SLIC superpixel stability under varying illumination, with and without gray-world color constancy — measured by boundary IoU, Variation of Information and neighbor stability.
