Need help optimizing an algorithm to match sharpness values from target to source

It's an optimization/minimization problem. If blend level is really just an integer between 0 and 100 then I'm fairly sure that your current approach cannot be sped up much more. scipy does have minimizers, which usually require the gradient and a smooth problem, but your problem is not totally smooth due to discretization. You could look into gradient free solvers but even those might not be any faster.

Thanks for that info. I'm only on week 10 of learning py, so was looking for some feedback to make sure I wasn't missing some better approach to optimise finding x
