Core Concepts
Introducing GiCiSAD, a novel framework addressing critical challenges in Skeleton-based Video Anomaly Detection.
Abstract
Introduction to the importance of Skeleton-based video anomaly detection.
Challenges faced in SVAD datasets: spatio-temporal dependencies, region-specific discrepancies, and infinite variations.
Overview of GiCiSAD framework with three modules: Graph Attention-based Forecasting, Graph-level Jigsaw Puzzle Maker, and Graph-based Conditional Diffusion Model.
Experimental results showcasing superior performance compared to existing methods on four benchmark datasets.
Comparison with state-of-the-art methods in terms of AUROC scores and parameter efficiency.
Ablation studies on individual components, conditioning mechanisms, types of graph-based Jigsaw puzzles, and number of subgraphs.
Conclusion highlighting the effectiveness of GiCiSAD in addressing challenges in SVAD.
Stats
Achieving this demands a comprehensive understanding of human motions.
Extensive experiments on four widely used skeleton-based video datasets show that GiCiSAD outperforms existing methods with significantly fewer training parameters.
