Abstract:
1. A system for providing an adjusted image of a scene, the scene including a foreground object and a background object, the system comprising: an optical assembly that is adjustable to alternatively be focused on a first focal area and a second focal area that is different than the first focal area; a capturing system coupled to the optical assembly, the capturing system capturing a first frame of the scene when the optical assembly is focused at the first focal area, and subsequently capturing a second frame of the scene when the optical assembly is focused at the second focal area; and a control system that analyzes at least one of the frames and divides the first frame into a plurality of first image segments, each first image segment being substantially homogeneous in color and including a plurality of pixels, the control system analyzes the first image segments using a segment based energy cost function and the first frame and the second frame, and the control system uses graph cut techniques to solve the energy cost function to determine that one of the first image segments corresponds to one of a portion of the foreground object and a portion of the background object.
