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

resonator causing fluctuations in the relaxation time on Q of the crystal. Handel has derived a flicker spectrum for fluctuations in the cross section of a scattering

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

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
