Hi,

There is an output variable featureStatus in Optical Flow APIs (fcvTrackLKOpticalFlowu8, fcvTrackLKOpticalFlowu8_v2 etc). The available documentation says this corresponds to "status of each feature" and nothing more.

I assume featureStatus=1 means the point is being tracked and 0 means it is not. But sometimes, I am getting featureStatus=-2 for some of the points.

Can anybody tell me what featureStatus = -2 actually mean?

Thanks,

Rohit

Hi,

Apologize for unclear documentation. Yes featureStatus=1 means the point is being tracked and any other values mean tracking failed for that point.

Cheers,

-Jeff
