We show, that the histogram equalization works significantly faster than the successive mean
quantization transform.
Sarkar solved the problem based on Angle
Quantization Index Modulation (AQIM) within STDM framework [11].
By smoothing the transformed values over time, a better overall consistency could be achieved, although the initial selection of reference points might prove problematic, particularly since skipping the
quantization step would be very costly in terms of computational effort, especially considering that video formats are often high-resolution.
Although QL quantizer provides almost constant SQNR in the wide dynamic range of variances, even better results can be achieved with switched
quantization technique.
Since non-uniform block sizes are used, we need
quantization matrices of sizes suitable for the 16 different block sizes.
while Signal to
Quantization Noise Ratio (SQNR), representing the more indicative parameter for the quantizer performance assessment, is defined as [1-3]:
After applying the
quantization, the compression ratio must be calculated to see the efficiency of the algorithm.
In order to meet the requirements of the discrete time MDP approach, a
quantization method is applied to approximate the continuous process of BOT.
As it is typically the case regarding the
quantization of systems with an infinite number of degrees of freedom, also in the
quantization of the Dirac field in curved space-time, one must face the issue of ambiguity, or lack of uniqueness in the
quantization procedure.
