Mind the Student: Behavioral and Contextual Cues for Automated Engagement Prediction in Online Learning
Alperen Kantarci, Visvanathan Ramesh, Gemma Roig
The prediction of student engagement from the online tutoring videos is difficult because engagement is a multidimensional construct comprising distinct behavioral, emotional, and…
Evaluation of Randomization through Style Transfer for Enhanced Domain Generalization
Dustin Eisenhardt, Timothy Schaumlöffel, Alperen Kantarci +1
Deep learning models for computer vision often suffer from poor generalization when deployed in real-world settings, especially when trained on synthetic data due to the well-known…
A Survey on Computer Vision based Human Analysis in the COVID-19 Era
Fevziye Irem Eyiokur, Alperen Kantarcı, Mustafa Ekrem Erakın +8
The emergence of COVID-19 has had a global and profound impact, not only on society as a whole, but also on the lives of individuals. Various prevention measures were introduced ar…
Bias-Aware Face Mask Detection Dataset
Alperen Kantarcı, Ferda Ofli, Muhammad Imran +1
In December 2019, a novel coronavirus (COVID-19) spread so quickly around the world that many countries had to set mandatory face mask rules in public areas to reduce the transmiss…
Face-Dubbing++: Lip-Synchronous, Voice Preserving Translation of Videos
Alexander Waibel, Moritz Behr, Fevziye Irem Eyiokur +7
In this paper, we propose a neural end-to-end system for voice preserving, lip-synchronous translation of videos. The system is designed to combine multiple component models and pr…
Shuffled Patch-Wise Supervision for Presentation Attack Detection
Alperen Kantarcı, Hasan Dertli, Hazım Kemal Ekenel
Face anti-spoofing is essential to prevent false facial verification by using a photo, video, mask, or a different substitute for an authorized person's face. Most of the state-of-…
MOCCA: Multi-Layer One-Class ClassificAtion for Anomaly Detection
Fabio Valerio Massoli, Fabrizio Falchi, Alperen Kantarci +3
Anomalies are ubiquitous in all scientific fields and can express an unexpected event due to incomplete knowledge about the data distribution or an unknown process that suddenly co…
Offline Signature Verification on Real-World Documents
Deniz Engin, Alperen Kantarcı, Seçil Arslan +1
Research on offline signature verification has explored a large variety of methods on multiple signature datasets, which are collected under controlled conditions. However, these d…
Thermal to Visible Face Recognition Using Deep Autoencoders
Alperen Kantarcı, Hazım Kemal Ekenel
Visible face recognition systems achieve nearly perfect recognition accuracies using deep learning. However, in lack of light, these systems perform poorly. A way to deal with this…
Blockchain-Based Electronic Voting System for Elections in Turkey
Rumeysa Bulut, Alperen Kantarcı, Safa Keskin +1
Traditional elections satisfy neither citizens nor political authorities in recent years. They are not fully secure since it is easy to attack votes. It threatens also privacy and…
