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 practicaly selected sw tools for image processing. THe main activities are focused on the proces of authomatic image classification. Main objectives can be summarized as ollows: 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. Suppervised and unsuppervised approaches New methods of image classification. Image processing of RADAR and hyperspectral data. Change detection.

Assessment methods

An exam has the form of written test on theory of image processing. Elaboration of all practical excercises and successul pass the practical test at the end of the term are two necessary conditons to pass the exam. Practical test with the use of computer.
