4. Sub-Band VQ Codes In order to evaluate the discrete codes generated by the autoencoder described in the previous section, we have also created a method of encoding the N-frames of spectral information using a more traditional approach based on sub- band vector quantization (VQ). Unlike ...
Experimental results on speech spectrogram coding demonstrate that the binary codes produce a log-spectral distortion that is approximately 2 dB lower than a sub-band vector quantization technique over the entire frequency range of wide-band speech. Opens in a new tab © 2007 ISCA....
quantization parameter for INTRA pictures –15; rate control used- TMN-8; annexes- all off; elements TR, ESTUF and EOS are left error free. As i n H.263 bit stream there exist several syntactical elements and to reduce compl exity and granularity, different ...
Rather than using only truncated unary binarization for the syntax element representing the delta quantization parameter and context coding all of the resulting bins as in the prior art, a different binarization is used and only part of the resulting bins are context coded, thus reducing the worst...
The quantized coefficients and associated information, such as motion vectors, quantization parameters, etc., are then encoded by the entropy coder 26. Intra-coded frames/slices (i.e. type I) are encoded without reference to other frames/slices. In other words, they do not employ temporal ...
METHOD FOR BINARY CODING OF QUANTIZATION INDICES OF A SIGNAL ENVELOPE, METHOD FOR DECODING A SIGNAL ENVELOPE AND CORRESPONDING CODING AND DECODING MODULESA module (402) for binary coding of a signal envelope, comprising coding module (502) for coding a variable length first mode. The coding ...
Although binary coding has been popular for implementing both techniques, n-ary coding (known as Product Quantization) is also very effective for Distance Estimation. However, their relative performance has not been studied for Subset Indexing. We investigate whether binary or n-ary coding works ...
METHOD FOR BINARY CODING OF QUANTIZATION INDICES OF A SIGNAL ENVELOPE, METHOD FOR DECODING A SIGNAL ENVELOPE AND CORRESPONDING CODING AND DECODING MODULESThe invention concerns a module (402) for binary coding of a signal envelope, comprising a coding module (502) of a first variable length mode...
In recent years, binary coding of image features, such as local binary patterns and local phase quantization, have become popular in a large variety of image quantification tasks. Lately, some non-binary codings, such as local ternary pattern, have been proposed to improve the performance of ...
