Geometric algebra and Garamon

Garamon stands for Geometric Algebra Recursive and Adaptative Monster. It is a C++ library generator synthesizing efficient C++ libraries implementing geometric algebras in both low and higher dimensions, with any arbitrary metric. The library generator is designed to produce easy to install, easy to use, effective and numerically stable libraries. The design of the libraries is based on a prefix tree data structure and a recursive scheme for high dimensions.

MesoNet: a Compact Facial Video Forgery Detection Network

MesoNet is a deep learning program dedicated to to automatically and efficiently detect face tampering in videos, and particularly focuses on two recent techniques used to generate hyper-realistic forged videos: Deepfake and Face2Face.

Computer graphics vs. photgraphic images

This paper presents a method to distinguish computer graphics from real photographic images. The program is based on a convolution neural network focussing on the statistical properties of the images, including image noise, to efficiently classify the data.
