### Lecturer: Prof. Fred Hamprecht; Teaching Assistant: Steffen Wolf

*Note: Over the semester holidays, I've had much time to think about the content that will best serve you in the future. As a result, the proposed curriculum has changed relative to an earlier version of the web page. Please make sure this is still what you are looking for.*

*The course is suitable for Master students as well as ambitious Bachelor students.*

Computer vision is one of the few key technologies that is changing the face of our society and that will deeply impact our lives in the future. However, modern computer vision pipelines build on a wealth of quite different concepts and techniques that will leave most novices confused.

The aim of this lecture is to introduce nontrivial foundational algorithms and concepts that are used in many pipelines.

Most computer vision pipelines use a subset of the following:

- Regression
- Classification
- Feature extraction
- Cluster analysis
- Regularization
- Optimization
- Dimension reduction
- Matching

In response, we will study the following concepts.

## Contents

- Nonparametric regression (median filtering, robust smoothers, non-local means)
- Linear system theory (Fourier and friends)
- Bilinear decompositions (PCA and friends)
- k-means, multicut, modularity clustering, mean shift: ways of grouping a set of points, or of partitioning a graph
- Metric learning
- Dynamic programming and distance transforms, skeletonization
- Optimal transport
- Basics of either convolutional neural networks, or of computational photography (based on popular vote)

## Format

2 hours of lectures per week, pen and paper and python programming exercises.

## Prerequisites

The following are strictly required:

- multivariable calculus: gradients
- linear algebra: linear system of equations, eigenproblems
- probability theory: multivariate random variables
- knowledge of any programming language

## Literature

No single book covers the contents of this course; but the following are helpful:

- Birchfield: Image Processing and Analysis
- Jaehne: Digital Image Processing
- Vetterli, Kovacevic, Goyal: Foundations of Signal Processing
- Cormen, Leiserson, Rivest, Stein: Introduction to Algorithms
- Sonka, Hlavac, Boyle: Image Processing, Analysis, and Machine Vision
