Improved dictionaries for generalized bitplanes-based matching pursuits video coding using ridgelets
14 years 6 months ago
A novel decomposition of functions using generalized bitplanes has been recently proposed. Such a decomposition maps a function into a set of indexes, thus performing quantization...
