Hi,

On video input which works with Farneback optical flow and TV-L1 optical flow, the deepflow code from the opencv contrib repository outputs NaN values. This does not happen deterministically, but happens randomly at some frame. It works with expected output sometimes but at times outputs NaN.

Has any one faced similar problems with deep flow code ?

Version:

git describe --long

• opencv: 3.0.0-beta-0-gae4cb57
• opencv-contrib: 3.0.0-beta-0-g08699f1

Input video:

Thanks and regards,
