Graph based transform
WebMar 1, 2024 · Graph Signal Processing (GSP) extends Discrete Signal Processing (DSP) to data supported by graphs by redefining traditional DSP concepts like signals, shift, filtering, and Fourier transform among others. This thesis develops and generalizes standard DSP operations for GSP in an intuitively pleasing way: 1) new concepts in GSP are often … WebThere are three main transformations of graphs: stretches, reflections and translations. Translations are a type of graphical transformation where the function is moved. To …
