Abstract: In High Efficiency Video Coding (HEVC), the coding efficiency of intra frames is much lower than inter frames. If the bits allocated to intra frames are not sufficient to improve their quality, the quality fluctuation… read more here.

Abstract: We consider lambda and anisotropic deformations of the SU(2) principal chiral model and show how they can be quantized in the Hamiltonian formalism on a lattice as a suitable spin chain. The spin chain is… read more here.
