  • Associate Professor, Computer Science
Dr. Amos Johnson’s research background is in pattern recognition and pattern discovery. 

He has developed pattern recognition algorithms to identify people from their walking patterns and created algorithms to discover patterns in video surveillance data. As an associate professor, he has focused on providing students with the best teaching instruction possible and creating enhancements to their learning process in computer science.

  • Interactive Visual Art Modules
    Using image recognition techniques to interact with a virtual reality world, we studied
    the effectiveness of using non-traditional input devices and simulation environments
    that include artistic elements to increase a student’s interest in science, technology,
    engineering, and math.
  • Learning Variations of a Single Predefined-Activity
    Created soft systems to learn the various ways a single predefined activity may occur
    from a limited amount of visual data of the activity. Using this information, the
    system will classify a new instance of the activity as either belonging to one of the
    many variations of the activity or as an abnormally.
  • Gait Recognition
    Our gait-recognition method recovers static body and stride parameters of subjects as
    they walk. Our technique does not directly analyze the dynamic gait patterns, but uses
    the action of walking to extract relative body parameters.
  • Parametric Metrics to Estimate Performance of Biometric Techniques
    Parametric metrics, expected confusion and transformed expected confusion, are
    developed as means to estimate verification performance of biometric techniques.
  • Method to Predict Cumulative Match Characteristic Performance
    A method to predict cumulative match characteristic (CMC) curve performance for
    large galleries of individuals using data from a significantly smaller gallery is derived.
