NPGR032

Digital image processing in practice : MFF-CUNI

COURSE DESCRIPTION

Practical examples and applications of Image Processing and Pattern Recognition

A seminar that offers a deepening of the theory of digital image processing and recognition of the NPGR002 course and its supplementation with experiments and practical applications in the MATLAB programming language environment. Attention is paid to digital image digitization, preprocessing (noise suppression, contrast enhancement, blur removal), edge detection, geometric transformations, flag-based object description, and automatic recognition (classification) methods. The course can be taken concurrently with NPGR002, as a practicum, or independently after completing NPGR002.

LABS

We are going to take a step into the world of Image Processing using python. In order to do that, you should know the basics of Python. Please go through the following section before attending labs. Necessary information for completing all labs will be provided here. If you have any questions please contact novozamsky@utia.cas.cz

The exercises will be in Czech, but all materials and texts will be in English.

REQUIREMENTS

Zoom account - the webcam will be on !

GitHub account

Gmail account for Colab is recommended
