Cíle předmětu
The aim of this lecture is to introduce all the basic image transforms used in digital image processing. It covers the operations of changing the image content or transforming the original data into a 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.
Výstupy z učení
After completing the course, the student should be able to:
- analyze the image data in a frequency domain;
- discuss the problems in the field of frequency analysis;
- propose her/his own efficient and optimized compression methods;
- demonstrate the general principles of compression algorithms;
- use wavelet and Fourier transform appropriately;
- solve the tasks focused on image restoration;
- appropriately use the resampling algorithms and understand their results

Metody hodnocení
During the semester, the students are required to solve the selected team project. The final defense of this project takes place during the last week of the semester. The students must successfully pass this defense in order to be allowed to take the final exam. The 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 a chance to explain or finalize those solutions from the written part that are incomplete.
