Really interesting! Thank you Hendrik. I have been looking for a transformation function that would convert a rotating point (pixel) into a point captured by a rolling shutter. Something like:
transfo[{x_,y_},v_,frm_] ---> {xt,yt}
Where v is the rotation speed, and from the frame number in the video. Any rotating image could then be converted into a roller shutter captured video frame by frame. But that's work for the future...
