using optimize to reverse engineer an image filtering stack

[Sebastien Binet]

hi there,

I am trying (for fun) to replicate the "Crema" image filter from Instagram.

I have devised a couple of image kernels that kind of replicate it, even if it's a bit off.

Obviously, I have a test image and its result from Instagram that I can compare with the image resulting from my procedure.
I was mentally toying with the idea of refining the 13 parameters I came up with by shoveling everything to optimize.Minimize.

But, I am not completely certain it is sound: perhaps a genetic algorithm-based approach would be better suited ?

what do you think ?
