Multiple energy function active contours applied to CT and MR images

Reports on the work on active contour models (or snakes) undertaken as part of the SAMMIE project (AIM project A2032) on the development of advanced segmentation aids for object demarcation in MR and CT images. Active contour models (or snakes) are a special form of deformable models, characterised by their property of dynamic deformation to an image from an original given shape. This deformation is controlled through the minimisation of an energy function. An overview is given of the Computer Tomography (CT) and Magnetic Resonance (MR) imaging modalities. This is followed by a section introducing active contour models, or snakes. The adopted active contour model is then detailed, followed by a breakdown of the work undertaken in developing this for CT and MR images
