Area of Science:

  • Fusion energy research
  • Plasma physics
  • Image analysis

Background:

  • The Joint European Torus (JET) facility generates vast amounts of visual data from high-speed cameras.
  • Efficiently retrieving specific visual patterns from this data is crucial for operational analysis and research.
  • Existing retrieval methods may struggle with pattern variations and location independence.

Purpose of the Study:

  • To develop an advanced image retrieval system for the JET facility.
  • To enable the identification of similar visual patterns across different camera frames.
  • To facilitate faster and more accurate analysis of experimental data.

Main Methods:

  • Development of an image retrieval system utilizing a database of JET high-speed visible camera images.
  • Implementation of a morphological pattern recognition approach.
  • Encoding images into a character-based format to convert pattern searching into a character-matching problem.

Main Results:

  • The system successfully retrieves groups of frames exhibiting patterns similar to a user-selected input pattern.
  • Pattern recognition is performed independently of the pattern's location within the image frame.
  • The transformation of image data into character strings simplifies and optimizes the search process.

Conclusions:

  • The developed system provides an effective solution for retrieving similar visual patterns from JET experimental data.
  • Morphological pattern recognition, when encoded into characters, offers a robust method for image retrieval.
  • This technique enhances the ability to analyze and understand complex plasma phenomena captured by high-speed cameras.
