track objects using video

[belyileha]

Hello,

I would like to track one's face within a continous video.  After simulating aquisition and working with several images to train Vision Builder to follow the face, how do I then switch to continuous video mode and have it still look for the same object (face)?  In other words, what are the sequences of steps within Vision Builder to do this? What do we do with the 'Simulate Acquisition' step and in what order do I place the "Acquire Image(continuously) step in the inspection?

Many thanks.

Hi belyileha,

How is the face moving? Does it move/rotate?

You would have to do your processing frame by frame (essentially a video, but in actuality a series of images) instead of on a video. You should just be able to use the Match Pattern step and then process each image to match to that pattern.

As a side note, one option could be to subtract each subsequent image from the previous. If the face is moving (or can be isolated), then you would be able to track its movement.
