Dr Michael Morgan
4 points * Two 1-hour lectures and one 2-hour laboratory class per week plus six 1-hour tutorials * Second semester * Clayton * Prerequisite: CSC3140 or PHS2431
Objectives On successfully completing this subject a student should have a working knowledge of digital image formation and the representation of digital data; be familiar with the complexities of the human vision system; understand the problems associated with pattern recognition and machine vision; be able to design and implement linear filters in 1D; be familiar with non-linear filtering and morphological operations; be acquainted with the methods of Hough and distance transforms and the representation of digital images in these domains; understand how to reconstruct images from projections and the significance of this process in tomography; be able to apply image processing to selected areas of science, technology and medicine.
