Image based biometry

Subject description

The course relies mostly on computer vision, as most biometrics technologies are based on it. Students interested in cutting edge technology, much of which is still in a research stage, are the intended target for the course. The main content (will evolve due to developments in the field):


  1. Biometry basics

  2. Biometrical modalities

  3. Structure of a typical biometric system

  4. Recognition/verification/identification

  5. Metrics

  6. Conditions for correct comparisons of the systems (databases, frameworks)

  7. Performance and usefulness of the systems

  8. Computer vision as the foundation of the biometric systems


  9. Fingerprint

    1. Acquisition

    2. Quality assessment and quality improvement

    3. Processing

    4. Singular points, minutiae, ridges

    5. Matching


  10. Iris

    1. Acquisition

    2. Quality improvement

    3. Processing (segmentation, normalization, coding)

    4. Feature points

    5. Matching


  11. Face

    1. Acquisition

    2. Sub-modalities

    3. Processing

    4. Feature points (appearance/
      model/texture-based approach)

    5. Matching


  12. Gait

    1. Acquisition

    2. Influence of dynamics

    3. Processing (appearance/
      model-based approach)

    4. Dynamic feature points

    5. Matching


  13. Ear

    1. Acquisition

    2. Processing

    3. Feature points

    4. Matching


  14. Multi-biometric systems / multi-modality / fusions

  15. Key problems of modalities/systems (research challenges)


The lectures introduce the approaches and explain their operation. At tutorial the knowledge is applied to practical problems in Matlab and open source tools.

The subject is taught in programs

Objectives and competences

Objectives of the course:

  • Student gains good overview over the biometry and with it related computer vision methods that set foundations of biometric systems.

  • Student gets acquainted with the flow of the research work.

  • Student gets good foundation for doctoral study.

    Gained student competences:

  • Knows the terminology and principles of identity analysis.
  • Knows the scope of the biometric technologies and their (dis)advantages.
  • Knows how the system works from the acquisition to decision.
  • Understands the processing flow for each biometric modality.
  • Knows some limitations of biometric systems.
  • Is able to critically consider older and newer modalities and how they can work together.
  • Is familiar with some open problems/challenges in biometry.

Teaching and learning methods

Lectures and tutorial, individual work on assignments/project, presentations of outcomes.

Expected study results

After successful completion of the course, students will be able to:

– explain the design cycle of the biometric system

– differentiate between specifics of different modalities

– choose computer vision algorithms for biometric pipeline

– implement biometric pipeline

– evaluate the quality of each step in the pipeline

– build multi-biometric system

– argument the choice of metrics, databases, protocols

– identify open research questions

– write a technical report.
