Efficient Rate Control for Lossless Mode of JPEG2000
Jicheng An, Zixing Cai · IEEE Signal Processing Letters · 2008
This letter introduces a simple yet efficient rate control method, which is designed for lossless mode of JPEG2000. This method uses a fractional upward shift of bitplane to simulate more precise subband weighting. Compared to the previous integer upward shift of the bitplane, it achieves superior performance at most bit-rates without the cost of increased computational complexity.
