SpecGuard: Spectral Projection-based Advanced Invisible Watermarking
Inzamamul Alam, Md Tanvir Islam, Khan Muhammad +1
Watermarking embeds imperceptible patterns into images for authenticity verification. However, existing methods often lack robustness against various transformations primarily incl…
FakeChain: Exposing Shallow Cues in Multi-Step Deepfake Detection
Minji Heo, Simon S. Woo
Multi-step or hybrid deepfakes, created by sequentially applying different deepfake creation methods such as Face-Swapping, GAN-based generation, and Diffusion methods, can pose an…
SpecXNet: A Dual-Domain Convolutional Network for Robust Deepfake Detection
Inzamamul Alam, Md Tanvir Islam, Simon S. Woo
The increasing realism of content generated by GANs and diffusion models has made deepfake detection significantly more challenging. Existing approaches often focus solely on spati…
Saliency-Aware Diffusion Reconstruction for Effective Invisible Watermark Removal
Inzamamul Alam, Md Tanvir Islam, Simon S. Woo
As digital content becomes increasingly ubiquitous, the need for robust watermark removal techniques has grown due to the inadequacy of existing embedding techniques, which lack ro…
LoLI-Street: Benchmarking Low-Light Image Enhancement and Beyond
Md Tanvir Islam, Inzamamul Alam, Simon S. Woo +3
Low-light image enhancement (LLIE) is essential for numerous computer vision tasks, including object detection, tracking, segmentation, and scene understanding. Despite substantial…
UGAD: Universal Generative AI Detector utilizing Frequency Fingerprints
Inzamamul Alam, Muhammad Shahid Muneer, Simon S. Woo
In the wake of a fabricated explosion image at the Pentagon, an ability to discern real images from fake counterparts has never been more critical. Our study introduces a novel mul…
