Hi, thanks for this PR, this seems like a good idea. We're using Ruff now for code style checking and it had just a few little complaints - I think all it needs is to add a blank line after the new imports. Would you be OK to fix that and then I'm happy to merge when all the tests are happy. Thanks! Edit: Oh, and please do also add a |
postprocess submodule relies on OpenCV which takes nearly 15s to import on Raspberry Pi Zero 2 W with standard SD card. With this patch it drops to nearly 4s (depending on file cache).

Importing OpenCV on SD card is slow (~15sec).
This patch removes OpenCV import from the main path to speed up import time of imx500.
An alternative solution would be to use another library like Pillow which is faster to import and provide similar drawing performance.
