Is there a way to check if any object of interest lies completely inside the frame of an image/video. The object should not be partially present in the frame but it should be 100% visible.

just curious -- what's the context ? what do you need it for ?

I plan on using it to detect whether a plate of food is entirely in the frame or not. In a way to assist clicking pictures of food.

When you detect an object, you shoud get a contour or a rectangle or something that has a retrievable bounding box (perhaps with boundingRec()). Just check that all its points' coordinates are > 0 and less than height - 1 and width - 1.
