Abstract
According to embodiments herein, depth key compositing is the process of detecting specific desired portions/objects of a digital image using mathematical functions based on depth, in order to separate those specific portions/objects for further processing. In one particular embodiment, a digital visual image is captured from a video capture device, and one or more objects are determined within the digital visual image that are within a particular depth range of the video capture device. From there, the one or more objects may be isolated from portions of the digital visual image not within the particular depth range, and the isolated objects are processed for visual display apart from the portions of the digital visual image not within the particular depth range. Also, in certain embodiments, the detected portion of the digital image (isolated objects) may be layered with another image, such as for film production, or used for holographic projection.
