Course objectives

At the end of the course, students should be able to understand the basic approaches to digital image processing. Moreover, they should be able to use practically selected sw tools for image processing. The main activities are focused on the process of authomatic image classification. Main objectives can be summarized as follows: Hard copy images and digital images. Interpretation of hard copy imagery Principles of visual interpretation, interpretation keys Advantages and drawbags of hard copy imagery and visual interpretation Characteristics of digital imagery. Raster data format and its specific features Remotely sensed data chracter, A- D conversion. Basic types of image resolution Image Data storage. Comonn and specific data formats. Image compression. Auxiliary data. Basic steps of digital image data processing Preprocessing, radiometric and atmospheric corrections. Geometric correction and transformation. Image enhancement, image histogram. Principles of automatic classification. Supervised and unsupervised approaches New methods of image classification. Image processing of RADAR and hyperspectral data. Change detection. At the end of the course student should be able to understand basic image procesing (IP) methods explained in individual lectures. He/she would be able to explain when to apply individual IP methods and make reasoned decisions about preconditions that are necessary for proper utilization of IP methods in question. He/she would be able to work with information on satellite imagery preprocessing, make deductions based on acquired knowledge concerning IP methods and properly interpret and validate results of analysis.

Teaching methods

Lectures explaining basic terms of digital image processing and presenting individual examples step by step. Practical training based on 11 exercises that are solved using image processing software. Satellite imagery used within the practical courses.

Assessment methods

The exam has the form of a written test on theory of image processing. Elaboration of all practical excercises and successul practical test at the end of the term are two necessary conditions for passing the exam. Practical test with the use of computer.

Language of instruction

Czech
