German researchers have found a way to identify deep fake images by converting them to the frequency domain using the discrete cosine transform. The team, from the Ruhr-Universität Bochum and Casa ...

[Ottverse] has an interesting series in progress to demystify video compression. The latest installment promises to explain discrete cosine transforms as though you were five years old. We’ll… ...

…the Discrete Cosine Transform takes a set of N correlated (similar) data-points and returns N de-correlated (dis-similar) data-points (coefficients) in such a way that the energy is compacted ...
