Image Analysis
Bildanalys

FMA171F, 7.5 credits

Valid from: Autumn 2013
Decided by: FN1/Anders Gustafsson
Date of establishment: 2014-01-31

General Information

Division: Mathematics
Course type: Course given jointly for second and third cycle
The course is also given at second-cycle level with course code: FMA170
Teaching language: English

Aim

The aim of the course is to give necessary knowledge of digital image analysis for further research within the area and to be able to use digital image analysis within other research areas such as computer graphics, image coding, video coding and industrial image processing problems. The aim is also to prepare the student for further studies in e.g. computer vision, multispectral image analysis and statistical image analysis.

Goals

Knowledge and Understanding

For a passing grade the doctoral student must

• be able to explain clearly, and to independently use, basic mathematical concepts in image analysis, in particular regarding transform theory (in space as well as in the frequency domain), image enhancement methods, image compression and pattern recognition.
• be able to describe and give an informal explanation of the mathematical theory behind some central image processing algorithms (both deterministic and stochastic).
• have an understanding of the statistical principles used in machine learning

Competences and Skills

For a passing grade the doctoral student must

• in an engineering manner be able to use computer packages to solve problems in image analysis.
• be able to show good capability to independently identify problems which can be solved with methods from image analysis, and be able to choose an appropriate method.
• be able to independently apply basic methods in image processing to problems which are relevant in industrial applications or research.
• with proper terminology, in a well structured way and with clear logic be able to explain the solution to a problem in image analysis.
