Furthermore, we demonstrate that it is not feasible to find a kernel matrix that precisely characterizes ... filter in terms of the DCT-KLD (Kullback-Leibler divergence of discrete cosine transform) ...

The Discrete Wavelet Transform (DWT) has gained the reputation of being a very effective signal analysis tool for many practical applications. This paper presents an approach towards VLSI ...

For the filter kernel ... we multiply the two transforms to get the result at the figure’s bottom center. We can see that the 8-Hz frequency component of our input has been eliminated, and we can use ...

The discrete cosine transform, quantization, rounding, and truncation together form a transformation that (under the right conditions) leads to a predictable set of fixed points. Unlike watermarking, ...

In ordinary practice, we perform a spectral analysis on time-domain data. However, in step (6) above we are performing a discrete cosine transform on information that is already in the frequency ...
