Divide and Conquer: High-Resolution Industrial Anomaly Detection via Memory Efficient Tiled Ensemble

no code implementations7 Mar 2024 Blaž Rolih, Dick Ameln, Ashwin Vaidya, Samet Akcay

To overcome this challenge, we present the tiled ensemble approach, which reduces memory consumption by dividing the input images into a grid of tiles and training a dedicated model for each tile location.

Tensor Pooling Driven Instance Segmentation Framework for Baggage Threat Recognition

1 code implementation22 Aug 2021 Taimur Hassan, Samet Akcay, Mohammed Bennamoun, Salman Khan, Naoufel Werghi

Furthermore, to the best of our knowledge, this is the first contour instance segmentation framework that leverages multi-scale information to recognize cluttered and concealed contraband data from the colored and grayscale security X-ray imagery.

Competitive Simplicity for Multi-Task Learning for Real-Time Foggy Scene Understanding via Domain Adaptation

no code implementations9 Dec 2020 Naif Alshammari, Samet Akcay, Toby P. Breckon

For optimal performance in semantic segmentation, our model generates depth to be used as complementary source information with RGB in the segmentation network.

GANomaly: Semi-Supervised Anomaly Detection via Adversarial Training

9 code implementations17 May 2018 Samet Akcay, Amir Atapour-Abarghouei, Toby P. Breckon

Anomaly detection is a classical problem in computer vision, namely the determination of the normal from the abnormal when datasets are highly biased towards one class (normal) due to the insufficient sample size of the other class (abnormal).
