face morphing attacks generation algorithms

This repository contains several landmarked based and deep leaning (GAN) based face morphing attacks generation methods.

Attack Procedure

Existing Morphing Tools/Techniques

• Numerous easy-to-use morphing tools online e.g., [MorphThing], [3Dthis Face Morph], [Face Swap Online], [Abrosoft FantaMorph], [FaceMorpher], [MagicMorph].

• Techniques in literature

landmark-based morphing

• Works by obtaining landmark points on facial regions, e.g., nose, eye, and mouth.

• The landmark points obtained from two bona fide faces are warped by moving the pixels to different, more averaged positions,

• e.g. Delaunay triangulation: Affine transform, Alpha blending

• Post-processing: misaligned pixels generating artifacts; ghost-like artifacts

deep learning based morphing

• Most are based on Generative Adversarial Networks (GAN)

• Most adopt CNN as basic architecture

• Works by embedding the images in the intermediate latent space, e.g. StyleGAN : Linear combination, Synthesize using Generator

• Post-processing if needed: Synthetic-like generation artifacts
