the two same images #60

Can I use this project to generate a flow map by the two same images

sniklaus commented 1 year ago

I am afraid that I have difficulties trying to follow, could you elaborate? You want to insert the same exact image twice and estimate the flow between those identical images?

zkjkak commented 1 year ago

图片 I found out from a paper that it uses two identical images as image_one and image_two, then to generate the optical flow map of .flo. But I can only get a blank optical flow map by doing this. I don't know if this makes sense.

Two identical images have zero optical flow between them, you might want to reach out to the authors of the paper you are quoting from and ask them to clarify.
