Leveraging Selective Prediction for Reliable Image Geolocation
Apostolos Panagiotopoulos, Giorgos Kordopatis-Zilos, Symeon Papadopoulos
Reliable image geolocation is crucial for several applications, ranging from social media geo-tagging to fake news detection. State-of-the-art geolocation methods surpass human per…
DnS: Distill-and-Select for Efficient and Accurate Video Indexing and Retrieval
Giorgos Kordopatis-Zilos, Christos Tzelepis, Symeon Papadopoulos +2
In this paper, we address the problem of high performance and computationally efficient content-based video retrieval in large-scale datasets. Current methods typically propose eit…
Leveraging EfficientNet and Contrastive Learning for Accurate Global-scale Location Estimation
Giorgos Kordopatis-Zilos, Panagiotis Galopoulos, Symeon Papadopoulos +1
In this paper, we address the problem of global-scale image geolocation, proposing a mixed classification-retrieval scheme. Unlike other methods that strictly tackle the problem as…
Operation-wise Attention Network for Tampering Localization Fusion
Polychronis Charitidis, Giorgos Kordopatis-Zilos, Symeon Papadopoulos +1
In this work, we present a deep learning-based approach for image tampering localization fusion. This approach is designed to combine the outcomes of multiple image forensics algor…
