Overview

Grundlagen der BildverarbeitungDr. R. Nestler

The lecture Basics of Image Processing and Pattern Recognition(Image Processing 1) deals with methods for solving recognition tasks with camera-based technical systems. Nowadays, camera-based ("seeing") technical systems are widely used in automation technology, robotics, medical technology, surveillance technology and in the automotive sector.

The course initially focuses on digital images with scalar pixel values (so-called grey-scale images), which have to be evaluated in terms of concrete tasks. The overall goal of this evaluation is the interpretation of the image content on different levels of abstraction. For this purpose, the images have to be processed, transformed, converted, analysed and finally classified in their technically accessible form in order to derive relevant contents and statements. In the course, essential methods, procedures and algorithms will be considered and discussed in the context of concrete applications from practice.

In addition to the purely informatic aspects of digital image processing, the lecture also teaches important contexts for the creation and description of digital images.

As a result, participants should be able to understand classic processing chains for solving image-based recognition tasks, implement them themselves for simple and recurring image pre-processing tasks, and confidently navigate this interdisciplinary field of knowledge. For current areas of application of image processing in artificial intelligence, such as deep learning, the best conditions are created for better understanding and targeted use of the processing steps of pixel-based image processing laid out in the architectures.

The course is accompanied by an exercise, in which the lecture contents are reviewed, deepened and simple BV tasks are worked on with a prototyping software for image processing solutions (VIP-Toolkit). Numerous teaching examples are provided for the lecture.

Building on the contents taught in the lecture, the student can use the acquired knowledge in further courses of the bachelor and master studies, e.g.

  • System technology and system theory of image processing

as well as further courses on applied image processing / artificial intelligence at the TU Ilmenau.
