Geometric active contour, or geodesic active contour (GAC) [8] or conformal active contours [9] employs ideas from Euclidean curve shortening evolution. Contours split and merge depending on the detection of objects in the image. These models are largely inspired by level sets, and have been extensively employed in medical image computing.
(a) Reconstruct projection rays from the image points (b) Estimate the nearest point of each projection ray to a point on the 3D contour (c) Estimate the pose of the contour with the use of this correspondence set (d) goto (b) The above algorithm does not account for images containing an object that is partially occluded.
It is closely related to the active appearance model. It is also known as a "Smart Snakes" [ 1 ] method, since it is an analog to an active contour model which would respect explicit shape constraints.
The boundary encoding leverages the fact that regions in natural images tend to have a smooth contour. This prior is used by Huffman coding to encode the difference chain code of the contours in an image. Thus, the smoother a boundary is, the shorter coding length it attains.

Contour integration is closely related to the calculus of residues, [4] a method of complex analysis. One use for contour integrals is the evaluation of integrals along the real line that are not readily found by using only real variable methods. [5] Contour integration methods include:

Video of spiral being propagated by level sets (curvature flow) in 2D.Left image shows zero-level solution. Right image shows the level-set scalar field. The Level-set method (LSM) is a conceptual framework for using level sets as a tool for numerical analysis of surfaces and shapes.
