I am calculating optical flow of video frames using the follwing basic lines of code of optical flow. I am also getting good results. My code is running well. I just want to have knowledge about optical flow.
flow = estimateFlow(opticFlow,I) % estimates optical flow between two consecutive video frames.
Where opticFlow is the object for optical flow estimation.
I want to ask, in the line of code written above, with respect to which frame I am calculating the optical flow. It's written there consecutive frames but from where it is taking the input of previous frame for the current frame I written in the code.
If someone can please solve my query, it will be of great help.
In case, you need more clarity on the question please let me know
