Abstract
Active contour models (commonly called "snakes") have
shown themselves to be a powerful and flexible
paradigm for many problems in image understanding.
Active contour models are now applied to the problem of
detecting coronary blood vessels in cardiac angiography
images, an important medical image understanding
problem. Given two endpoints along a vessel, active
contour models are used to find the vessel within a
single angiography image. Snakes will also be employed
to detect vessels across multiple frames, a task which
involves computing local measures of interframe
vessel motion. This is particularly important, since
often the most useful information to clinicians is
found in the motion of a vessel across the
cardiac cycle.
