Abstract
A system is provided that is configured to encode an image in accordance with a variable resolution image format. The variable resolution image format allows the specification of a number of windows in terms of their location and resolution. The image can be decomposed into a minimum number of square superpixels such that all specified windows are at the assigned resolution or better. By encoding one image where only critical portions are at the high resolution while less critical portions are at intermediate or lower resolutions, the number of bits that need to be transmitted from the system to a remote host subsystem can be dramatically reduced.
