NDAA09027U Signal and Image Processing (SIP)
MSc programme in Computer Science
MSc programme in Physics
The course introduces basic computational, statistical, and mathematical techniques for representing, modeling, and analysing signals and images. Signals and images are measurements, which change with time and/or space, and these measurements typically originate from a physical system ordered on a grid. Examples are 1 dimensional sound, 2 dimensional images from a consumer camera, 3 dimensional reconstructions from medical scanners, and movies.
Applications include: removal of high frequency noise in sound, detecting and segmenting objects in images, and reconstruction of 3 dimensional Computed Tomography images (CT) from X-ray images.

Criteria for exam assesment
To get maximum grade the student must successfully be able to:
Discuss and apply the theoretical basics of digital signal and image processing
Reflect the linear processing of signals and design and apply digital filters for discrete signals.
Explain and identify different types of noise, design noise removal algorithms for image restoration and solve statistical linear inverse filtering problems for images.
Compare Fourier analysis to multiresolution analysis, relate the fundamental concepts of multiresolution analysis, and perform time/space-frequency analysis for signals and images.
Analyze the image histograms, and transform the images to another forms to enhance the visual content of the image or to facilitate easier interpretation and processing.
Explain fundamental image segmentation approaches and implement them to extract homogeneous regions on the images.
Relate and illustrate elementary representation methods in description of image content
