The course will include selected advanced topics in motion perception using computer vision. Concrete topics will change each year according to trends in this fast developing field. Potential topics will include: (i) optical flow, (ii) tracking by templates, (iii) tracking by discriminative models, (iv) Bayesian probabilistic tracking, (v) deep learning for tracking, (iv) long-term tracking. The course is composed of the lectures in which we will cover the relevant theory and assignments in which the students will implement the basic techniques and solidify the theory.
Coursework consists of 5 mandatory two-week assignments (complete them on your own with consultations with the assistant and professor), starting within the first weeks of the course. The assignments are uniformly distributed throughout the semester. More info available at e-classroom.
The course is VERY mathematical and requires understanding of mathematical derivations and a skill to transfer them into programming. The course is thus ranked among the toughest (estimated by students) among all courses at FRI. It is appropriate ONLY for students with solid mathematical and programming skills. The estimated work load per assignment is 10-20h of work. You should select this course only if you are prepared to invest a lot of effort.

The syllabus is based on a selection of modern statistical natural learning techniques and their practical use. The lectures introduce the main tasks and techniques, explain their operation and theoretical background. During practical sessions and seminars the gained knowledge is applied to language practical task using open source tools. Student investigate and solve assignments, based on real-world problems form English and Slovene languages.

2. Language resources: corpuses, dictionaries, thesauruses, networks and semantic data bases, overview of tools.
3. Linguistics: phonology and morphology, syntactical analysis, formal grammars.
4. Using automata and grammars: automata and algorithms for searching strings, syntax parsing, dependency parsing.
5. Part-of-speech tagging: types of tags, lemmatization, ngrams, Hidden Markov model, rule-based tagging.
6. Computational and lexical semantics: semantic representations, rule-to-rule approaches, semantic role labelling.
7. Clustering words and text similarity measures: cosine distance, language networks and graphs, WordNet, vector representation, vector weighting, sematic correlation.
8. Text mining: adaptation of classification methods to the specifics of text, support vector machines for language, feature selection.
9. Deep networks for text: document representations for deep neural networks, autoencoders, recurrent neural networks.
10. Text summarization: text representations, matrix factorization, multi-document summarization, extractive methods, query based methods.

The course introduces techniques and procedures for analysis of biomedical signals and images like: cardiology signals (electrocardiogram - ECG), neurophysiology signals (electromyogram - EMG, electroencephalogram - EEG), medical images (computed tomography – CT images) with the emphasis on problems of biomedical researches. We will recognize how we can automatically, non-invasive and punctually, within 24-hour electrocardiogram signals, detect heart beats, classify them, and detect transient ischaemic disease, which is one of the most terrible heart diseases; and if we do not discover it punctually, it may lead to heart infarct. We will see how we can, using some non-linear signal processing techniques, analyze electromyograms recorded from the abdomen of a pregnant women, early during pregnancy (23 rd week), estimate, or try to predict, danger of pre-term birth. We will recognize techniques of analyzing electroencephalographic signals, which are recorded from the head of a person, with the aim of human-computer interaction, without using classic input devices. We will also recognize techniques of analysis of 3-dimensional tomographic images with the aim of extraction and visualization of anatomic structures of human body organs. The topics cover: representation of international standardized databases of signal samples (MIT/BIH DB, LTST DB, TPEHG DB, EEGMMI DS, BCI DB, CTIMG DB), techniques of feature extraction from signals and images (band-pass filters, morphological algorithms, principal components, Karhunen-Loeve transform, sample entropy, contour extraction), noise extraction, techniques of visualization of diagnostic and morphology feature-vector time series, and anatomic structures, analysis of feature-vector time series, spectral analysis, modelling, event detection, clustering, classifications, as well as metrics, techniques and protocols to evaluate performance and robustness of biomedical computer systems. Coursework consists of three seminars, quiz during lectures, and final exam.
