NDAA09027U Signal and Image Processing (SIP)

Volume 2018/2019

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.
