A new quantization optimization algorithm for the MPEG advanced audio coder using a statistical sub-band model of the quantization noise

By organiz- ing the transform coefficients into trees and using a parent- children relation, they produce an embedded bitstream where the first bits represent the most important bits

The logarithmic model substitutes both the linear and quadratic models used in H.264/AVC rate controller, and does not need any complexity measure. Objective and subjective

On the other hand, the second class constraints of Plebanski formulation, supposed to be the starting point of the SF approach, lead to Dirac brackets and a modified symplectic
