Synopsis:

Digital image processing × image analysis × computer vision. Interpretation, its significance for images. Objects in images. Distance transform (DT). Brightness histogram. Image acquisition from the geometric and radiometric point of view. Fourier transform . Sampling theorem. Filtering in frequency domain. PCA. Brightness scale transformation, geometric transformations, interpolation. Image registration. Image processing in spatial domain. Convolution, correlation. Noise filtering. Edge detection. Linear and nonlinear methods. Mathematical morphology. Image compression. Color images. Texture. Segmentation of objects in images. Objects description in images and their recognition.

Requirements:

It is possible to obtain 100 points in total. Fulfillment of the exercises during the practices corresponds to maximum 60 points and the written exam test from the lectures assures maximum 40 points. Classification <50 F, 50-59 E, 60-69 D, 70-79 C, 80-89 B, 90-100 A
