Behavioral recognition system

TL;DR: In this article, a method and a system for analyzing and learning behavior based on an acquired stream of video frames is presented. But the method is not suitable for real-time applications.
Patent

Semantic representation module of a machine-learning engine in a video analysis system

TL;DR: In this article, a machine learning engine is described that is configured to recognize and learn behaviors, as well as to identify and distinguish between normal and abnormal behavior within a scene, by analyzing movements and/or activities (or absence of such) over time.
Patent

Long-term memory in a video analysis system

TL;DR: In this paper, a long-term memory used to store and retrieve information learned while a video analysis system observes a stream of video frames is disclosed, where the size of a feature dimension (used to determine the similarity between different observed events) may grow dynamically as necessary, depending on the actual events observed in a sequence of videos.
Patent

Identifying anomalous object types during classification

TL;DR: In this article, a self-organizing map and adaptive resonance theory (SOM-ART) network is used to discover object type clusters and classify objects depicted in the image data based on pixel-level micro-features that are extracted from the image.
Patent

Video surveillance system configured to analyze complex behaviors using alternating layers of clustering and sequencing

TL;DR: In this article, techniques for a video surveillance system to learn to recognize complex behaviors by analyzing pixel data using alternating layers of clustering and sequencing are described, where each layer identifies what events and behaviors are common and which are unusual.
