- Abstract summary: We propose a novel regularisation term that takes into account the existent identity information in both and promotes the creation of two latent vectors.
We evaluate our proposed method in five different types of morphing in the FRLL dataset and evaluate the performance of our model when trained on five distinct datasets.

- Abstract: Morphing attacks are one of the many threats that are constantly affecting
deep face recognition systems. It consists of selecting two faces from
different individuals and fusing them into a final image that contains the
identity information of both. In this work, we propose a novel regularisation
term that takes into account the existent identity information in both and
promotes the creation of two orthogonal latent vectors. We evaluate our
proposed method (OrthoMAD) in five different types of morphing in the FRLL
dataset and evaluate the performance of our model when trained on five distinct
datasets. With a small ResNet-18 as the backbone, we achieve state-of-the-art
results in the majority of the experiments, and competitive results in the
others. The code of this paper will be publicly available.

Face Recognition (FR) systems can suffer from physical (i.e., print photo) and digital (i.e., DeepFake) attacks.

Deepfakes are realistic face manipulations that can pose serious threats to security, privacy, and trust.
Existing methods mostly treat this task as binary classification, which uses digital labels or mask signals to train the detection model.
We propose a novel paradigm named Visual-Linguistic Face Forgery Detection(VLFFD), which uses fine-grained sentence-level prompts as the annotation.

Models [0.0]
Morphed face images can be used to impersonate someone's identity for various malicious purposes.
Existing MAD techniques rely on discriminative models that learn from examples of bona fide and morphed images.
We propose a novel, diffusion-based MAD method that learns only from the characteristics of bona fide images.
