Foreground subject detection

摘要

Classifying (300) pixels in a digital image includes receiving (302) a primary image from one or more image sensors. The primary image includes a plurality of primary pixels. A depth image from one or more depth sensors is also received (308). The depth image includes a plurality of depth pixels, each depth pixel registered to one or more primary pixels. The depth image and the primary image are cooperatively used to identify (324) whether a primary pixel images a foreground subject or a background subject.
