Discovered that RAFT wasn't actually working due to an issue with the function that got the flows. There was a missing "elif". So, the RAFT flow would get calculated and stored in the variable 'r', but then 'r' would always be overwritten by the default Farneback at the end. We were fooling ourselves into thinking that was RAFT, when in actuality the RAFT flow is invalid and causes an error if actually used.
- Changed function call for flow methods so that this can never happen. Now, each case returns directly.
- Added to deprecation utils for now. We can remove the RAFT to Farneback conversion when we get RAFT working
Realignment of the way I handled frame indexes in motion routines to align everything more clearly
Major improvement to motion using prev_img during cadence!
- added a prev_img during cadence so that there is a prev_img to refer to for the flow
Fixed color matching issue with first frame on Image and Video Init modes
- first frame color match can't be done beforehand, so it's done afterwards. But, that normally makes for a very bad first frame. So, I added a redo for it to clean up the color matched image on first frame.
Major improvement to RANSAC
- switched to use SIFT for feature matching instead of Lucas-Kanade
- changed all border_mode to REFLECT_101, which matched how optical flow handled it, removed all the excess silly border_mode translations. This works much better.
