System and method for identifying a region of interest in a digital image
A system and method for identifying a region of interest in a digital image. A first and second images of a scene may be obtained from a respective first and second points of view. Following an acquisition of a first image from a first point of view, a subsequent image may be automatically acquired upon determining that a second view point is achieved. Based on two or more images of a scene, a background object may be removed from an image to produce an image that only includes a foreground object or a region of interest.
1. A method of analyzing digital images, the method comprising:
acquiring, by a camera, a first image of a scene from a first point of view;
presenting said first image on a display screen;
automatically detecting, by the camera, movement of the camera to a second point of view of the same scene captured by the first image;
upon said detection, automatically causing a camera to acquire a second image of the scene from the second point of view;
separating a foreground object included in the scene based on pixels included in one of the first and second images and excluded from the other one of the first and second images; and
improving, by using the second image, presentation of said separated foreground object in the image displayed on the display screen.
2. The method of claim 1 , comprising automatically identifying a set of points of view assumed by the camera, acquiring a respective set of images and iteratively improving, in real-time, separation of the foreground object.
3. The method of claim 1 , wherein said automatically causing a camera to acquire a second image comprises instructing a user to move the camera in order to acquire at least said second image of the scene from said second point of view.
4. The method of claim 1 , comprising:
acquiring an additional image of the scene from an additional point of view;
improving by using the additional image, in real-time, presentation of said separated foreground object; and
presenting the improved presentation on the display screen.
5. The method of claim 1 , comprising identifying the foreground object.
6. The method of claim 1 , wherein the first and second images are automatically selected from a provided set of images.
7. The method of claim 1 , comprising sending an image of the foreground object to a remote computer.
8. An article comprising a non-transitory computer-readable storage medium, having stored thereon instructions, that when executed on a computer, cause the computer to:
receive, from a camera, a first image of a scene from a first point of view;
present said first image on a display screen;
automatically detect movement of the camera to a second point of view of the same scene captured by the first image;
upon said detection, automatically cause a camera to acquire a second image of the scene from the second point of view;
separate a foreground object included in the scene based on pixels included in one of the first and second images and excluded from the other one of the first and second images; and
improve, by using the second image, presentation of said separated foreground object in the image displayed on the display screen.
9. The article of claim 8 , wherein the instructions when executed further result in identifying a set of points of view assumed by the camera, receiving a respective set of images and iteratively improving, in real-time, separation of the foreground object.
10. The article of claim 8 , wherein the instructions when executed further result in said automatically causing a camera to acquire a second image comprises instructing a user to move the camera in order to acquire at least said second image of the scene from said second point of view.
11. The article of claim 8 , wherein the instructions when executed further result in:
acquiring an additional image of the scene from an additional point of view;
improving by using the additional image, in real-time, presentation of said separated foreground object; and
presenting the improved presentation on the display screen.
12. The article of claim 8 , wherein the instructions when executed further result in identifying the foreground object.
13. The article of claim 8 , wherein the instructions when executed further result in automatically selecting the first and second images from a provided set of images.
14. The article of claim 8 , wherein the instructions when executed further result in sending an image of the foreground object to a remote computer.
