displacement Values issue

[moumenabdelhafidh]

Hello everyone,

I juste started to use the open source matlab code ''open optical flow'.

In comparaison with PIV software (VIC 2D) i'm finding a huge difference in pixel displacement (factor x10) in both direction.

Please find in attachement both VIC2D and Open Optical Flow results,

I think that the problem is coming from lamda1 and lamda2 factors, if it 's the problem how to fix it? and haow to fix it without a reference like VIC2D

Kind regards
