system, existing coding solutions which suit for the CSV system are: 1) JPEG [20] based solution MJPEG-differential pulse code modulation (MJPEG-DPCM) [21], 2) uniform scalar quantization (USQ) based solution USQ-DPCM [22], 3) H.264/AVC Intra codec [23], and 4) HEVC Intra codec [...
Here, uniform scalar quantization of watermarked documents is investigated theoretically, extending results from theory of dithered quantization, and experimentally. The watermark is embedded by an independent additive pseudo-noise sequence. The statistical distribution of the quantization errors depending on ...
A quantization method based on fuzzy inference filter is proposed. First, the original image is decomposed to obtain wavelet coefficients. Second, a fuzzy inference filter is used to non-uniformly determine whether a wavelet tree contains higher entropy energy. A general if-then-else structure is ...
In[30], an analysis of the noise power generated by the uniform scalar quantization when the input signal meets the Gaussian distribution has been carried out and a table for the optimal values of finite quantization range for different quantization levels is provided, which contributes to our ...
quantization module that maps the continuous feature vectors into a discrete set of tokens from a learned codebook. As those tokens are more abstract, they reduce the complexity of the features by retaining important features while filtering out all the irrelevant information. Because of that ...
Physical systems in a curved space-time have generated growing interest due to their self-consistent geometro-dynamics. Among the different space-time topologies, the choice of S 3 x R manifold is very attractive because of the group prop

For a uniform distribution of source samples, we determine the corresponding optimal scalar quantizers and their average distortions. For non-uniform distributions and vector quantization, we provide a high-resolution analysis of the minimum possible average distortion. Applications to sensor and cellular...
Uniform - a type qualifier indicating a read-only variable passed to a shader from the CPU side of the program. These values will not change within a draw call, and are available to every shader that declares it. Varying - a type qualifier indicating a variable that can change within the...
