2004 Proceedings of the 6th ACM SIGMM international workshop on Multimedia information retrieval - MIR '04  
From an analysis of broadcast soccer video, we propose a query description model based on Basic Semantic Unit Composite Petri-Nets (BSUCPN) to automatically detect significant events within soccer video  ...  Firstly we define a Basic Semantic Unit (BSU) set for soccer videos based on identifiable feature elements within a soccer video, Secondly we design Composite Petri-Net (CPN) models for semantic queries  ...  CONCLUSIONS AND DISCUSSIONS In this paper, based on analyzing of soccer video characteristics, we proposed a query description model for soccer video using Basic Semantic Unit Composite Petri-Nets (BSUCPN  ...

A model of fuzzy spatio-temporal knowledge representation and reasoning based on high-level Petri nets

Slobodan Ribaric, Tomislav Hrkac
2012 Information Systems  
In this paper we present a model of fuzzy spatio-temporal knowledge representation and reasoning based on high-level Petri nets.  ...  The scheme is based on the high-level Petri nets called Petri nets with fuzzy spatio-temporal tokens (PeNeFuST).  ...  Formal analysis of the FuSpaT model In general, analysis problems for Petri net-based models, such as safeness, boundedness, conservation, etc., are based on the reachability tree [39, 56] , which is  ...

Unsupervised human activity analysis for intelligent mobile robots

Paul Duckworth, David C. Hogg, Anthony G. Cohn
2019 Artificial Intelligence  
Our presented framework models each extended observation as a probabilistic mixture over the learned activities, meaning it can learn human activity models even when embedded in continuous video sequences  ...  Analogously to information retrieval on text corpora we use generative probabilistic techniques to recover latent, semantically meaningful, concepts in the encoded observations in an unsupervised manner  ...  Examples of these models in the literature include Petri Nets (PNs) for interpreting activities in surveillance images [Borzin et al., 2007] , grammar models and Inductive Logic Programming (ILP) for  ...

Augmented transition networks as video browsing models for multimedia databases and multimedia information systems

Shu-Ching Chen, S. Sista, Mei-Ling Shyu, R.L. Kashyap
Proceedings 11th International Conference on Tools with Artificial Intelligence  
An ATN and its subnetworks can model video data based on di erent granularities such as scenes, shots and key frames. Multimedia input strings are used as inputs for ATNs.  ...  The details of how to use multimedia input strings to model video data are also discussed. Key frame selection is based on temporal and spatial relations of semantic objects in each shot.  ...  As shown in 4], ATNs need fewer nodes and arcs to represent a multimedia presentation compared with Petri-net models such as OCPN 9] .  ...

We use both the process model and ODM to perform a series experimental works in CBD, including the cross-validation of a component metrics set for JavaBeans, a case study on the influence of practitioners  ...  Techniques: We propose a process model for ESE, aligned with current experimental best practices, and combine this model with a measurement technique called Ontology-Driven Measurement (ODM).  ...  Composite components have as many threads of control as internal active components. The execution semantics of components is formalized as a Petri net interpretation [Nierstrasz 02].  ...

These two processes of modelling and memorization happen in real time while interspersing with each other in a manner they almost seem as if they are one process.  ...  In this paper we provide a simplified model of this complicated relationship between emotions, perceptions and our behaviour to produce a model that can be used in software agents and humanized robots.  ...  Acknowledgement The first author is a post-doctoral fellow sponsored by the Portuguese Foundation for Science and Technology.  ...
