1. A method of providing a video signal comprising: capturing pixel data associated with a conferencing environment; determining whether a captured pixel is included within a defined region of interest (ROI) defined in part by a number of boundaries comprising at least three boundaries defined in part by three equations including r +g <1 that use red (r) pixel values associated with a normalized red axis and green (g) pixel values associated with a normalized green axis; designating the captured pixel as a ROI pixel if the captured pixel is included within the defined ROI; and, using an augmented detection region associated with the defined ROI to enhance distinguishing participant features as part of allocating more of a bandwidth budget to human participants and less of the bandwidth budget to other visual aspects of a surrounding scene of the conferencing environment.
