CS413 Image and Video Analysis

CS413 15 CATS (7.5 ECTS) Term 1


Option - MEng CS and DM, MSc CS, MSc DA


CS118, CS131 or equivalent knowledge and experience

Academic Aims

The module aims to teach the fundamentals of digital image processing, image and video analysis. In particular, it will present the mathematics and algorithms that underlie image analysis techniques such as filtering, edge detection, feature detection, tracking and 3D reconstruction. It will also present how these tools are used in algorithms for image and video segmentation, motion estimation, stereo reconstruction, video analysis, object detection and recognition.

The course will enable computer science undergraduates to apply their mathematical knowledge and understanding of algorithms to problems in image and video processing: from preprocessing, to quantitation, video compression and video interpretation, machine learning for image analysis. The methods have numerous applications e.g. in medicine, biology, robotics (computer vision), surveillance, security, biometrics, database searching, TV and entertainment.
