Extraction of arbitrarily shaped objects using stochastic multiple birth-and-death dynamics and active contours.

Kulikova, M.S. and Jermyn, I.H. and Descombes, X. and Zhizhina, E. and Zerubia, J. (2010) 'Extraction of arbitrarily shaped objects using stochastic multiple birth-and-death dynamics and active contours.', in Computational Imaging VIII: proceedings of SPIE-IS&T Electronic Imaging. Bellingham, WA: SPIE, p. 753306. Proceedings of SPIE., 7533 (7533).


We extend the marked point process models that have been used for object extraction from images to arbitrarily shaped objects, without greatly increasing the computational complexity of sampling and estimation. The approach can be viewed as an extension of the active contour methodology to an a priori unknown number of objects. Sampling and estimation are based on a stochastic birth-and-death process defined in a space of multiple, arbitrarily shaped objects, where the objects are defined by the image data and prior information. The performance of the approach is demonstrated via experimental results on synthetic and real data.
