Hard-Attention for Scalable Image Classification
Athanasios Papadopoulos, Paweł Korus, Nasir Memon
Can we leverage high-resolution information without the unsustainable quadratic complexity to input scale? We propose Traversal Network (TNet), a novel multi-scale hard-attention a…
Empirical Evaluation of PRNU Fingerprint Variation for Mismatched Imaging Pipelines
Sharad Joshi, Pawel Korus, Nitin Khanna +1
We assess the variability of PRNU-based camera fingerprints with mismatched imaging pipelines (e.g., different camera ISP or digital darkroom software). We show that camera fingerp…
FiFTy: Large-scale File Fragment Type Identification using Neural Networks
Govind Mittal, Pawel Korus, Nasir Memon
We present FiFTy, a modern file type identification tool for memory forensics and data carving. In contrast to previous approaches based on hand-crafted features, we design a compa…
Neural Imaging Pipelines - the Scourge or Hope of Forensics?
Pawel Korus, Nasir Memon
Forensic analysis of digital photographs relies on intrinsic statistical traces introduced at the time of their acquisition or subsequent editing. Such traces are often removed by…
Content Authentication for Neural Imaging Pipelines: End-to-end Optimization of Photo Provenance in Complex Distribution Channels
Pawel Korus, Nasir Memon
Forensic analysis of digital photo provenance relies on intrinsic traces left in the photograph at the time of its acquisition. Such analysis becomes unreliable after heavy post-pr…
Large-Scale and Fine-Grained Evaluation of Popular JPEG Forgery Localization Schemes
Pawel Korus
Over the years, researchers have proposed various approaches to JPEG forgery detection and localization. In most cases, experimental evaluation was limited to JPEG quality levels t…
