XSA-MAD: Cross-modal Semantic Alignment for Morphing Attack Detection

Jie Jin, Mahiro Tokumasu, Yu Makino +2

Morphing attacks pose a serious threat to face recognition systems. However, existing image-based morphing attack detection (MAD) methods often generalize poorly to unseen generati…

Face Re-morphing: Differential Morphing Attack Detection via Feature-Space Similarity Changes

Jie Jin, Masakatsu Nishigaki, Tetsushi Ohki

Face morphing attacks pose a serious threat to face recognition systems because a single morphed document image can be matched to multiple contributors. Differential morphing attac…

Leveraging Intermediate Features of Vision Transformer for Face Anti-Spoofing

Mika Feng, Koichi Ito, Takafumi Aoki +2

Face recognition systems are designed to be robust against changes in head pose, illumination, and blurring during image capture. If a malicious person presents a face photo of the…

Enhancing Remote Adversarial Patch Attacks on Face Detectors with Tiling and Scaling

Masora Okano, Koichi Ito, Masakatsu Nishigaki +1

This paper discusses the attack feasibility of Remote Adversarial Patch (RAP) targeting face detectors. The RAP that targets face detectors is similar to the RAP that targets gener…

LabellessFace: Fair Metric Learning for Face Recognition without Attribute Labels

Tetsushi Ohki, Yuya Sato, Masakatsu Nishigaki +1

Demographic bias is one of the major challenges for face recognition systems. The majority of existing studies on demographic biases are heavily dependent on specific demographic g…

Multibiometrics Using a Single Face Image

Koichi Ito, Taito Tonosaki, Takafumi Aoki +2

Multibiometrics, which uses multiple biometric traits to improve recognition performance instead of using only one biometric trait to authenticate individuals, has been investigate…

PDH : Probabilistic deep hashing based on MAP estimation of Hamming distance

Yosuke Kaga, Masakazu Fujio, Kenta Takahashi +2

With the growth of image on the web, research on hashing which enables high-speed image retrieval has been actively studied. In recent years, various hashing methods based on deep…
