CVPR 2025 Workshop

Overview

Anomaly detection, and the synonymous topics of novelty and out-of-distribution detection, represent an important and application-relevant challenge within both computer vision and the broader field of pattern recognition. In its simplest formulation, anomaly detection targets the identification of samples which deviate from an obtained approximation to the true distribution of normality for a given dataset. As such anomalies represent unexpected eventualities or outliers in the scope of a given task. The notion of detecting them effectively and efficiently has been sought after for many real-world applications including medical diagnosis, airport security screening, industrial inspection, or crowd control.

However, anomaly detection is far from a simple task due to the challenges of accounting for all forms with which an anomaly may be present. It is typically impossible for any given dataset to account for the complete anomalous variability as they represent an unbounded (open set) distribution of possible deviations from the distribution of normality. Established supervised techniques are therefore prone to suffer from heavy classification bias or over-fitting.

To these ends, we now see the rise of a complex and vibrant set of learning-based paradigms addressing the anomaly detection task – varying across both the fully/semi/un-supervised and few/one/zero shot axes of recent computer vision and pattern recognition research. This workshop brings together researchers of both industry and academia to present and discuss recent developments, opportunities and open challenges in this area. The workshop will also host an anomaly detection challenge, to encourage the development and benchmarking new algorithms for realistic yet challenging tasks.
