Abstract
A method for processing image data includes quantizing a region in a frame with an initial quantizer level. It is determined whether an amount of bits required for encoding the region after quantizing the region with the initial quantizer level is within a bit allocation budget. The region is re-quantized if the amount of bits is not within the bit allocation budget.
