AUPIMO: Redefining Visual Anomaly Detection Benchmarks with High Speed and Low Tolerance

1 code implementation3 Jan 2024 Joao P. C. Bertoldo, Dick Ameln, Ashwin Vaidya, Samet Akçay

Recent advances in visual anomaly detection research have seen AUROC and AUPRO scores on public benchmark datasets such as MVTec and VisA converge towards perfect recall, giving the impression that these benchmarks are near-solved.

Exploring Racial Bias within Face Recognition via per-subject Adversarially-Enabled Data Augmentation

no code implementations19 Apr 2020 Seyma Yucer, Samet Akçay, Noura Al-Moubayed, Toby P. Breckon

Whilst face recognition applications are becoming increasingly prevalent within our daily lives, leading approaches in the field still suffer from performance bias to the detriment of some racial profiles within society.

Multi-Task Learning for Automotive Foggy Scene Understanding via Domain Adaptation to an Illumination-Invariant Representation

no code implementations17 Sep 2019 Naif Alshammari, Samet Akçay, Toby P. Breckon

Joint scene understanding and segmentation for automotive applications is a challenging problem in two key aspects:- (1) classifying every pixel in the entire scene and (2) performing this task under unstable weather and illumination changes (e. g. foggy weather), which results in poor outdoor scene visibility.

Evaluation of a Dual Convolutional Neural Network Architecture for Object-wise Anomaly Detection in Cluttered X-ray Security Imagery

no code implementations10 Apr 2019 Yona Falinie A. Gaus, Neelanjan Bhowmik, Samet Akçay, Paolo M. Guillen-Garcia, Jack W. Barker, Toby P. Breckon

Subsequently, leveraging a range of established CNN object and fine-grained category classification approaches we formulate within object anomaly detection as a two-class problem (anomalous or benign).

Skip-GANomaly: Skip Connected and Adversarially Trained Encoder-Decoder Anomaly Detection

2 code implementations25 Jan 2019 Samet Akçay, Amir Atapour-Abarghouei, Toby P. Breckon

By contrast, we introduce an unsupervised anomaly detection model, trained only on the normal (non-anomalous, plentiful) samples in order to learn the normality distribution of the domain and hence detect abnormality based on deviation from this model.
