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.

DCT (Discrete Cosine Transform): A mathematical technique that converts spatial pixel data into frequency components, crucial for energy compaction in image and video compression.

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 ...

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 ...

The Fourier coefficients associated with the payoff function are then approximated via the socalled discrete cosine transform. The main advantage of the numerical approach proposed in this paper is ...
