enabling flexible incorporation of both image information and prior knowledge,
that makes deformable models easily adaptable to specific applications [4, 56].
This approach is discussed in more detail in Chapter 9.
15.4.1.2 Cell Association
Several strategies exist for performing interframe cell association. The simplest
is to associate each segmented cell in one frame with the nearest cell in a
subsequent frame, where nearest may not only refer to spatial distance between
boundary points or centroid positions [12, 44, 47]. It may refer to similarity in
terms of average intensity, area or volume, perimeter or surface area, major and
minor axis orientation, boundary curvature, angle or velocity smoothness, and
other features [28, 64]. Generally, the
