Next, the three YCbCr components are treated independently to a discrete cosine transform and quantization. This transforms each 8×8 pixel block into 64 discrete spatial frequencies.

The discrete cosine transform (DCT) remains a cornerstone of modern image and video compression techniques, enabling the decomposition of visual data into frequency components that can be ...

This is the Fourier Transform. You can thank it for providing the music you stream every day, squeezing down the images you see on the Internet into tiny little JPG files, and even powering your ...

Discrete Cosine Transform IP-ALDCT soft core is the unit to perform the Discrete Cosine Transform (DCT). It performs two-dimensional 8 by 8 point DCT for the period of 64 clock cycles in pipelined ...

The approach consists of approximating the probability density function by its Fourier cosine series expansion in a truncated domain. The Fourier coefficients associated with the payoff function are ...

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 ...
