Rate Control for Hierarchical B-picture Coding with Scaling-factors
—The coding performance can be further improved when the hierarchical B-picture coding is introduced into H.264/AVC. However, the existing rate control schemes can NOT work effic...

Multiscale recurrent pattern image coding with a flexible partition scheme
In this paper we present a new segmentation method for the Multidimensional Multiscale Parser (MMP) algorithm. In previous works we have shown that, for text and compound images, ...
