Course DatesSeptember 9th - 20th, 2013
 
Course AbstractThe course is designed to be an introduction to hyperspectral and multichannel images and their analysis in MATLAB environment. During the course, the students will learn how to extract the relevant information from their images as well as the fundamentals of the main multivariate analysis methods (chemometrics) applied. The course will be conducted by using in-house functions programmed in MATLAB. See the following link for further information (http://www.models.life.ku.dk/HYPERTools)

Teaching and learning Methods
- Contact Teaching: the basis of the course teaching will be done by presentations. Lectures in power-point plus examples/exercises with the computer. The students will be able to follow all the exercises in their own computers. - Learning: Apart from the exercises presented at class, the students will be given several exercises that the must solve for the report. - Educational approaches: This course is addressed to PhD student or advanced Master students. The educational background of the students will be different.
 
Learning Outcome
After the course the students will be able to apply basic multivariate data analysis to their own hyperspectral images using MATLAB as preferred platform. The course will focus on hyperspectral and multichannel images and their interpretation and analysis with multivariate methods (PCA, MCR, PLS, PLS_DA, etc). The methods treated will explicitly or implicitly cover the following application areas: classification, calibration, prediction, spectral resolution and interpretability of solutions.
 
Course Literature
