Initialisation-Free Active Contour SegmentationXianghua Xie, Majid Mirmehdi, Initialisation-Free Active Contour Segmentation. Proc. of International Conference on Pattern Recognition. September 2010. PDF, 1033 Kbytes.
We present a region based active contour model which does not require any initialisation and is capable of modelling multi-modal image regions. Its external force is based on statistically learning and grouping of image primitives in multiscale, and its numerical solution is carried out using radial basis function interpolation and time dependent expansion coefficient updating. The initialisation-free property makes it attractive to applications such as detecting unkown number of objects with unkown topologies.
