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

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 ...

The discrete Fourier-cosine transform (cos-DFT), the discrete Fourier-sine transform (sin-DFT) and the discrete cosine transform (DCT) are closely related to the discrete Fourier transform (DFT) of ...
