Digital Image Analysis (VS1) (U02593)

? Credit Points : 10 ? SCQF Level : 11 ? Acronym : PHY-4-VDigImAn

An introductory course on digital image processing techniques concentrating on the mathematical and physical models underlying the processing operations. Digital image representation and sampling aspects are followed by various processing techniques including point by point operations, noise models, filtering and de-convolution techniques. This course consists of lectures plus a short programming project.

Summary of Intended Learning Outcomes

On completion of this course a student should be able to demonstrate
understanding of and be able to solve problems on:
1)linear image formation and its underlying assumptions
2)digital representation of image, the discrete Fourier Transform, its properties and implementation, Shannon sampling theorem, interpolation to zeroth and first order
3)first order image statistics, point-by-point processing and histogram manipulation
4)fixed pattern noise and random noise including underlying physics of Gaussian additive noise and methods of it estimation
5)linear filtering in real and Fourier space, non-linear filters including shrink and expand, average threshold and median
6)image restoration by inverse and Weiner filter, outline of CLEAN and maximum entropy restoration
7)tomographic system and reconstruction by Fourier inversion and filtered back projection, outline of fan-beam system
