Course: Digital Image Processing

Department/Abbreviation: KEF/DZO

Year: 2021

Guarantee: 'doc. Ing. Luděk Bartoněk, Ph.D.'

Annotation: In this course, the students become acquainted with usages of computers in measurements and analysis of image information acquired from one-dimensional and two-dimensional CCD sensors. The first part of the course is devoted to a study of relation of digital image processing to other related disciplines, to digitalization of analog signals and to description of typical CCD sensors. The second part of the course is then focused on processing of image matrix and its geometrical, statistical and spectral evaluations. The attention is also concentrated on methods of recognition (symptomatic and structural) and analysis of geometrical shapes in the image.
