Photoshop tutorial showing how to transform a photo of someone or something into a portrait painted on a rough surface like cobblestones. Coach John Beam dies after being shot on college campus ...

The lifting scheme offers a refined approach to implementing the Discrete Wavelet Transform (DWT) by decomposing traditional convolution-based filtering into a succession of simple, in-place ...

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 efficiently ...

Abstract: The discrete cosine transform (DCT), introduced by Ahmed, Natarajan and Rao, has been used in many applications of digital signal processing, data compression and information hiding. There ...

In part 3 of this series, we used the inverse fast Fourier transform (IFFT) to create 100-Hz time-domain waveforms of various amplitudes and phases. We can also use the IFFT to create waveforms ...

The inverse transform can create a time-domain waveform where no waveform has been before. In part 2 of this series, we used the discrete Fourier transform to convert a waveform from the time domain ...

Add a description, image, and links to the discrete-cosine-transform topic page so that developers can more easily learn about it.

The purpose of this project was to build an algorithm that can understand a small library of 10 simple commands while being able to ignore, or distinguish from, unknown commands. I submitted this work ...
