The keeper's note

A camera-driven background subtraction method that automatically selects a background image to isolate a subject in the frame.

Abstract

A device, system, and method performs a camera driven background subtraction. The method being performed at an electronic device includes receiving information corresponding to an image-capturing device that is capturing an image. The method includes automatically selecting one of a plurality of image analysis mechanisms based upon the information. The method includes receiving the captured image captured by the image-capturing device. The method includes performing an image analysis using the selected image analysis mechanism on the captured image to determine a foreground and a background in the captured image.

Background

BRIEF DESCRIPTION OF THE DRAWINGS(1) FIG. 1 shows anelectronic device according to the exemplary embodiments.(2) FIG. 2 shows a method of processing an image according to the exemplary embodiments.DETAILED DESCRIPTION(3) The exemplary embodiments may be further understood with reference to the following description and the related appended drawings, wherein like elements are provided with the same reference numerals. The exemplary embodiments are related to a device and method for dynamically selecting a mechanism for an image analysis to determine foreground from background in a captured image. Specifically, the exemplary embodiments may determine image-capturing parameters to further determine a type of image analysis mechanism to be used. The exemplary embodiments may further be configured to utilize multiple image analysis mechanisms in which a feedback loop is created between the multiple image analysis mechanisms. Thus, the exemplary embodiments provide an improved image processing procedure with a higher confidence in identifying a foreground from a background in a captured image.(4) FIG. 1 shows an electronic device 100 according to the exemplary embodiments. The electronic device 100 may be any component within an image-capturing, processing, and broadcasting system. Specifically, the electronic device 100 may be configured with the image processing aspect of the system. For example, the electronic device 100 may be a server or a network component that is communicat

Claims

1. A method, comprising: at an electronic device, receiving information corresponding to an image-capturing device that iscapturing an image; automatically selecting one of a plurality of image analysis mechanisms based upon the information; receiving the captured image captured by the image-capturing device; performing an image analysis using the selected image analysis mechanism on the captured image to determine a foreground and a background in the captured image; selectinga further one of the image analysis mechanisms; determining secondary information generated by using the further image analysis mechanism; and incorporating the secondary information into determining the foreground and the background in the captured image. 10. An electronic device, comprising: a memory configured to store a captured image generated by an image-capturing device; and a processor receiving information corresponding to the image-capturing device, the processor automatically selecting one of a plurality of image analysis mechanisms based upon the information, the processor performing an image analysis using the selected image analysis mechanism on the captured image to determine a foreground and a background in the captured image, wherein the processor further selects a further one of the image analysis mechanisms, determines secondary information generated by using the further image analysis mechanism, and incorporates the secondary information into determining the foreground and the background in the captured image. 18. A non-transitory computer readable storage medium including a set of instructions executable by a processor, wherein the instructions, when executed, cause the processor to: receive information corresponding to an image-capturing device that is capturing an image; automatically selecting one of a plurality of image analysis mechanisms based upon the information; receiving the captured image captured by the image-capturing device; performing an image analysis using the selected image analysis mechanism on the captured image to determine a foreground and a background in the captured image, selecting a further one of the image analysis mechanisms; determining secondary information generated by using the further image analysis mechanism; and incorporating the secondary information into determining the foreground and the background in the captured image.
