Objectives and competences

The aims of this course are to cover selected existing and emerging topics in advanced computer vision, and to prepare students for teamwork, as well as independent work in research and development. 

Learning and teaching methods

The lectures provide a theoretical background on particular subjects together with practical examples in Matlab and Python. 

Practical work is being performed as the part of laboratory exercises, and is accomplished in the form of multiple assignments, acquainting students with computer vision algorithms. Students work in groups, consisting of two or three students, and the results are in the form of Matlab and Python code. After completing each part, students present their results to the assistant. 

Homework project addresses the particular problem from the machine vision domain, either robot vision or industrial machine vision applications. 

Intended learning outcomes

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

  • Explain the differences between human visual system and computer vision methods 
  • Decide, which of the advanced computer vision methods is appropriate for the problem at hand 
  • Implement modern computer vision algorithms 
  • Develop complex solutions for computer vision problems, made up of multiple advanced methods 
  • Judge the performance of computer vision methods on the available data 
  • Propose solutions to computer vision problems from the field of automation and robotics that require the use of the advanced and complex algorithms, including neural networks and other learnable algorithms.
