 Synopsis:

The subject teaches how to represent the twodimensional image in a computer, how to process it and interpret it. The first part of the subject deals with the image as with the signal without interpretation. Image acquisition, linear and nonlinear preprocessing methods and image compression will be explicated. In the second part, image segmentation and registration methods will be taught. Studied topics will be practiced on practical examples in order to obtain also practical skills.
 Requirements:

It is expected that the student is familiar with calculus, linear algebra, probability and statistics to the depth taught at FEL CVUT.
 Syllabus of lectures:

1. Digital image processing vs. computer vision. Role of interpretation. Objects in images. Digital image. Concepts.
2. Physical foundation of images. Image acquisition from geometric and radiometric point of view.
3. Brightness and geometric transformations, interpolation.
4. Fourier transform. Derivation of the sampling theorem. Frequency filtration of images. Image restauration.
5. Processing in the spatial domain. Convolution. Correlation. Noise filtration. Homomorphic filtration.
