Foreground subject detection
First Claim
Patent Images
1. A method of classifying pixels in a digital image, the method comprising:
- receiving a primary image from a primary image sensor, the primary image including a plurality of primary pixels;
receiving depth information from a depth sensor, the depth information useable to determine a depth of a subject imaged by a primary pixel; and
cooperatively using the primary image and the depth information to identify whether the primary pixel images a foreground subject or a background subject.

Abstract
Classifying pixels in a digital image includes receiving a primary image from a primary image sensor. The primary image includes a plurality of primary pixels. Depth information from a depth sensor is also received. The depth information and the primary image are cooperatively used to identify whether a primary pixel images a foreground subject or a background subject.

19. A method of classifying pixels in a digital image, the method comprising:
-
receiving a primary image from one or more primary image sensors, the primary image including a plurality of primary pixels; receiving one or more secondary images from one or more secondary sensors, the one or more secondary images useable to estimate a depth of a subject imaged by a primary pixel; and cooperatively using the primary image and the one or more secondary images to identify whether the primary pixel images a foreground subject.

20. A computing system, comprising:
-
an input for receiving a primary image from a primary image sensor, the primary image including a plurality of primary pixels; an input for receiving depth information from a depth sensor, the depth information useable to determine a depth of a subject imaged by a primary pixel; and a logic subsystem for identifying whether the primary pixel images a foreground subject or a background subject.
