Course objectives
The aim of this lecture is to introduce all the basic image transforms used in digital image processing. It covers the operations changing the image content or transforming the original data into different representation. At the end of this course, students should be able to: understand the basic principles of the image transforms; know the selected transforms; implement and apply the selected transforms; understand standard image compression algorithms; correctly resample images; use suitable image restoration algorithms.
Syllabus

  • Recursive filtering
  • Deconvolution
  • Image compression, loss/lossless compression, colour indexing, entropy, JPEG, MPEG, the use in image formats

Teaching methods
obtaining knowledge during lectures, obtaining skills by working with PC
Assessment methods
During semester, the students are required to solve the selected team project. The final defense of this project takes place during the last week of semester. The students must successfully pass this defense in order to be allowed to take the final exam. Final exam consists of written and oral form. The written part contains questions that verify the students' skills and experience in the given field of image processing. The oral part follows the written part. Here, the students have chance to explain or finalize those solutions from written part that are incomplete.
