For more general distortions you could obviate the 'blob' image and instead just optimize a gain and offset for every pixel independently. Seems ambitiously high dimensional but I was able to get this kind of thing to work effectively using SPSA ( https://www.jhuapl.edu/SPSA/ https://www.jhuapl.edu/SPSA/ ). Also basically the algorithm of evolutionary strategies in AI: https://openai.com/blog/evolution-strategies/ https://openai.com/blog/evolution-strategies/
