How would one use any of OpenCV's Optical Flow algorithms on a 360 degree panorama video stored in an equirectangular projection?
Doing this regularly would not account for the distortion, I think. Additionally how would one make sure there are no seams in the resulting optical flow field along the edges of this equirectangular projected image?
Take this video for example: https://www.youtube.com/watch?v=0Fz82Kog4H4
