Front-stage proxy objects provide a reference function capable of referencing the front stage object and including reference information relating to the front-stage proxy objects.

In particular embodiments, the multicolored scene graphic includes a focal graphic and a background graphic, wherein the background graphic appears blurry relative to the focal graphic to enhance the conspicuousness of the focal graphic.

A processor stores in memory a front-stage object and one or more rear-stage objects capable of being referenced from the front-stage object.

In accordance with a method for providing a distinct perceptual location for an audio source within an audio mixture, a foreground signal may be processed to provide a foreground perceptual angle for the foreground signal.

Likewise, a foreground line profile is determined which represents an average foreground background intensity along the native lines in the image.

The processes run in foreground and background mode within the IHS.

An echo canceller comprises foreground and background filters.

Each of the foreground and background pixels have a respective color value.

The switching between the foreground and background configurations can be done almost instantaneously.

The foreground and background images are combined (130) to form a compact document.

Preferably, the first lighting condition illuminates the background without illuminating the foreground object so that a silhouette of the foreground object is acquired in the first image.

And when the fixed constant equals to 1, the foreground picture can be represented in its original size, thus improving the fidelity of the foreground picture.

The controller contains a processor operative to perform a foreground command received from the host, wherein the processor performs the foreground command to completion without interruption.

A convex hull is generated from the foreground mask.

The object classification module (160) is connected to the foreground object grouping module (150) and generates object-level information related to the foreground object.
