WebDec 4, 2024 · Colorization-based image coding is a technique to compress chrominance information of an image using a colorization technique. The conventional algorithm applies graph Fourier transform to the colorization-based coding. In this algorithm, several pixels on the image are defined as vertices of the graph, and the chrominance values of that … WebOct 1, 2024 · GraphCut. An implementation of the graph cut algorithm with a custom GUI written in PyQt. Using the interface users mark the foreground and background of the image. Using this information, the program builds a graph from the image pixels where the weights between pixels represent the difference between them. To segment the image a …
