Motion Tracking A Wound on an all white coat
on May 30, 2014 at 2:31:57 pm

Hello Everyone:

I am trying to motion track a wound on a person wearing a white coat who has fallen. I tracked the fall fairly well because it was a straight fall. The challenge is when he starts to move around on the floor, the wound moves around with the camera. I can't stabilize it.

Any suggestions?

Many thanks,

Debbie

Please show us a screen grab of the shot in question WITHOUT the wound. Then we'll know what you're up against.

And know this: an article of clothing is not a planar surface. It has folds that move, form and deform as the subject moves. You could possibly be up against more than you think to create a convincing effect.

But with no screen shot, we can't tell.

Hi Dave:

You are so right. I recut it so that I did not need to add that element. It was impossible to track a moving object when what they were wearing was moving also.

Thank you so much

Best,

Debbie
