Method and apparatus for detecting vessel boundaries

摘要

Disclosed is a method and system for detecting a boundary of a vessel in an image. Edges in the image are detected. Edge detection is based on the change in intensity over some distance while varying the scale of the distance. A set of edges is then selected from the detected edges. An initial vessel boundary is determined based on the selected set, and a shape descriptor (e.g., one or more elliptical shape descriptors) is applied to the initial vessel boundary to determine a final vessel boundary.
