MMFace-DiT: A Dual-Stream Diffusion Transformer for High-Fidelity Multimodal Face Generation
Bharath Krishnamurthy, Ajita Rattani
Recent multimodal face generation models address the spatial control limitations of text-to-image diffusion models by augmenting text-based conditioning with spatial priors such as…
DOOMGAN:High-Fidelity Dynamic Identity Obfuscation Ocular Generative Morphing
Bharath Krishnamurthy, Ajita Rattani
Ocular biometrics in the visible spectrum have emerged as a prominent modality due to their high accuracy, resistance to spoofing, and non-invasive nature. However, morphing attack…
Time Frequency Analysis of EMG Signal for Gesture Recognition using Fine grained Features
Parshuram N. Aarotale, Ajita Rattani
Electromyography (EMG) based hand gesture recognition converts forearm muscle activity into control commands for prosthetics, rehabilitation, and human computer interaction. This p…
Unified Face Matching and Physical-Digital Spoofing Attack Detection
Arun Kunwar, Ajita Rattani
Face recognition technology has dramatically transformed the landscape of security, surveillance, and authentication systems, offering a user-friendly and non-invasive biometric so…
Social Media Authentication and Combating Deepfakes using Semi-fragile Invisible Image Watermarking
Aakash Varma Nadimpalli, Ajita Rattani
With the significant advances in deep generative models for image and video synthesis, Deepfakes and manipulated media have raised severe societal concerns. Conventional machine le…
