Abstract:
A method of tracking an object in a sequence of digital images, each said image formed from an array of pixels and having a one-dimensional feature, said method comprising the steps of:acquiring said sequence of images;displaying a first one of said images containing said object;selecting, in said first one of said images, at least one user-selected point on said object of interest adjacent said one-dimensional feature;finding, in said first one of said images, a feature point located on said one-dimensional feature adjacent said user-selected point;forming an initial polyline contour substantially outlining said one-dimensional feature in said first one of said images; andrecovering an optimal polyline contour in each of the other of said images, each said optimal polyline contour outlining said one-dimensional feature and including said feature point.
