Run noise estimation on a part of the image #24

Closed MerlijnWajer closed 2 years ago

MerlijnWajer commented 2 years ago

We probably only need to analyse a part of the image to get a decent sense of camera (or other) noise. Running it on the whole image takes quite some time (it's the most costly operation currently).
