Modelling and Simulation of Neuromorphic Datasets for Anomaly Detection in Computer Vision
Summary
The Anomalous Neuromorphic Tool for Shapes (ANTShapes) is a novel dataset simulation framework developed in the Unity engine to address the scarcity of neuromorphic vision datasets for anomaly detection. This framework simulates abstract, configurable 3D scenes with objects exhibiting randomly generated behaviors like motion and rotation. ANTShapes uses a statistical process, based on central limit theorem principles, to sample object behaviors and label anomalous actions. It can generate datasets with an arbitrary number of samples, along with label and frame data, by adjusting a few parameters. The tool supports the simulation of bespoke datasets for applications such as object recognition, localization, and anomaly detection, specifically for event-based computer vision research.
Key takeaway
For research scientists developing Spiking Neural Networks (SNNs) for anomaly detection, ANTShapes offers a critical solution to the limited availability of neuromorphic vision datasets. You should consider using this Unity-based simulation framework to generate highly customizable, abstract datasets, allowing for controlled experimentation with SNN learning characteristics before moving to more realistic scenarios. This tool enables focused evaluation of anomaly detection models by precisely defining and labeling anomalous behaviors.
Key insights
ANTShapes simulates neuromorphic vision datasets for anomaly detection, overcoming DVS data scarcity via configurable 3D scenes.
Principles
- Anomaly definition uses statistical deviation from expected behaviors.
