Hi, the python interface isn’t really meant for pixel level manipulation. You should write your code in C instead. There’s no way you can fit an image in the small heap space available in C. Most of the memory on the MCU is not accessible in Python world.

What algorithm are you trying to do by the way? Dehazing? Does that mean image sharpening? We have that built-in already.
