Abstract
Embodiments of the present invention include systems and methods for processing and coding image data. In one embodiment, image data is coded using a first image coding process. If a bit rate constraint is satisfied, the image data is output. If the bit rate constraint is not satisfied, the image data is coded using a second different coding process. In one embodiment, the second coding process is a layered coding process. In another embodiment, if the constraint is satisfied, quantization data may be included in the output, and may be coded using layered coding. Variable length coding processes and hardware implementations are further disclosed for efficient image processing.
