A METHOD OF BINARY CODING QUANTIZATION INDICES OF A SIGNAL ENVELOPE, A METHOD OF 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. According to ...
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....
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 ...

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 ...

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 ...
