Every camera sensor leaves unique traces on the acquired images that can be thought of as a camera fingerprint. This work presents an efficient algorithm for clustering images based …
Source camera identification represents a delicate, crucial but challenging task in digital forensics, especially when an image has to be used as a proof in a court of law. This paper …
S Khan - Multimedia Tools and Applications, 2022 - Springer
The paper presents a canopy based image clustering algorithm using normalized cross- correlation among the camera fingerprints as a decision criterion. The proposed framework …

This work presents a new camera fingerprint-based image clustering algorithm. The proposed algorithm is based on sorting the camera fingerprints according to information that …
This paper presents a method for Photo Response Non Uniformity (PRNU) pattern noise based camera identification. It takes advantage of the coherence between different PRNU …
S Khan, T Bianchi - ICASSP 2019-2019 IEEE International …, 2019 - ieeexplore.ieee.org
This work presents a reduced complexity image clustering (RCIC) algorithm that blindly groups images based on their camera fingerprint. The algorithm does not need any prior …
SN Mufti, S Khan - 2022 International Conference on IT and …, 2022 - ieeexplore.ieee.org
The blind clustering of images without any prior information is always challenging for forensics experts. The problem gets severe in the case of a large dataset where the …
