Find the Leak, Fix the Split: Cluster-Based Method to Prevent Leakage in Video-Derived Datasets

We propose a cluster-based frame selection strategy to mitigate information leakage in video-derived frames datasets. By grouping visually similar frames before splitting into training, validation, and test sets, the method produces more representative, balanced, and reliable dataset partitions.

Recognition of Abnormal Events in Surveillance Videos using Weakly Supervised Dual-Encoder Models

We address the challenge of detecting rare and diverse anomalies in surveillance videos using only video-level supervision. Our dual-backbone framework combines convolutional and transformer representations through top-k pooling, achieving 90.7% area under the curve (AUC) on the UCF-Crime dataset.
