IMAGE SEGMENTATION FROM FOCUS VARIED IMAGES USING GRAPH CUTS
First Claim
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 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 the control system determines if one the first image segments corresponds to a portion of the foreground object and or a portion of the background object.

Abstract
A system for providing an adjusted image of a scene includes an optical assembly, a capturing system coupled to the optical assembly, and a control system. The optical assembly is adjustable to alternatively be focused on a first focal area and a second focal area that is different than the first focal area. The capturing system captures a first frame of the scene when the optical assembly is focused at the first focal area, and a second frame of the scene when the optical assembly is focused at the second focal area. The first frame includes a plurality of first pixels and the second frame includes a plurality of second pixels. The control system analyzes the first frame and the second frame and utilizes graph cuts techniques to assign a depth label to at least a portion of the first frame.

10. 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 capturing a second frame of the scene when the optical assembly is focused at the second focal area, the first frame including a plurality of first pixels and the second frame including a plurality of second pixels; and a control system that analyzes the first frame and the second frame and determines if the first pixels corresponds to a portion of the foreground object and or a portion of the background object;
wherein the control system processes the first pixels that corresponds to a portion of the foreground object in a first fashion, and processes the first pixels that corresponds to a portion of the background object in a second fashion that is different than the first fashion. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A method for providing an adjusted image of a scene, the scene including a foreground object and a background object, the method comprising the steps of:
-
alternatively focusing an optical assembly on a first focal area and a second focal area that is different than the first focal area; capturing a first frame of the scene when the optical assembly is focused at the first focal area with a capturing system; capturing a second frame of the scene when the optical assembly is focused at the second focal area with the capturing system; dividing the first frame into a plurality of first image segments with a control system, each first image segment being substantially homogeneous in color; and determining if one the first image segments corresponds to a portion of the foreground object and or a portion of the background object with the control system. - View Dependent Claims (19, 20, 21, 22)

23. A method for providing an adjusted image of a scene, the scene including a foreground object and a background object, the method comprising the steps of:
-
alternatively focusing an optical assembly on a first focal area and a second focal area that is different than the first focal area; capturing a first frame of the scene when the optical assembly is focused at the first focal area with a capturing system, the first frame including a plurality of first pixels; capturing a second frame of the scene when the optical assembly is focused at the second focal area with the capturing system, the second frame including a plurality of second pixels; determines if the first pixels corresponds to a portion of the foreground object and or a portion of the background object with a control system; and artificially blurring the first pixels that correspond to the portion of the background object. - View Dependent Claims (24, 25, 26)
