Hello @leochlon , thanks for opening this PR!
There's quite a lot missing, reminder that ALL the functionalities of the slow processor should be in the fast processor.
This is quite a difficult processor to work on, and as I'm working on Sam2 at the moment, I might work on the fast image processor of Sam myself maybe we should put this PR on hold for now

hey @yonigozlan I tried one more time, most of the functionality and logic between slow and fast is now 1-1 but using similar logic to the base fast image processor. would be cool if this implementation addresses your comments above! |

@yonigozlan let me know what else here is blocking and more than happy to take a look, test suite is all passing on my end. |

Thanks for the PR, and sorry it didn't make it in! This branch is based on v4, and v5 is very different, so rather than rebasing we'd love to invite you to open a new PR against
Closing this one in the meantime, thanks again! |
