Physical Models for Edge Finding: Snakes
Abstract:A snake is an elastic spline with dynamics determined by internal and external forces - it is a physical model for a one-dimensional curve. In this report, we use a snake to find and track features of interest in images by constructing forces which guide the snake to those features. Construction of these forces requires consideration of the "material" properties of elastic curves and the resulting dynamics and of the image processing required to generate an external force related to features of interest.
