The basic topics of the subject are techniques of 2D bio-signal processing, discrete 2D transforms, linear filtering, image reconstruction from projection, 3D reconstruction, 2D signal analysis (distortion and noise identification, wavelet decomposition, edge detection, segmentation, texture analysis), lossless and lossy compression, quality classification, 2D bio-signal processing in medicine (US, mammography, microscopic imaging, etc.)


Teaching takes place in the form of self-study with regular consultations. In addition to the examination, a written study is required by the student on the subject.

Syllabus of lectures:

1. 2D discrete transformations, DFT, Hadamard

2. Discrete cosine transformation

3. Wavelet decomposition and its utilization in 2D bio-signal analysis

4. Basic geometrical transformations

5. Mathematical model of the camera

6. Morphological image analysis, erosion, dilatation, morphological opening and closing, morphological filtering and its properties

7. Shape characteristics of objects in the image

8. Segmentation and thresholding (1).

9. Segmentation and thresholding (2).

10. FT, Cosine, Sine, Hadamard, Haar, Karhunen-Loeve transformations.

11. Image restoration techniques (1).

12. Image restoration techniques (2).

13. Inverse filtering

14. Wiener filtering.
