IEEE International Conference on Acoustics, Speech, and Signal Processing | Conferencia: | 25th IEEE International Conference on Acoustics, Speech, and Signal Processing, ICASSP 2000 | Resumen: | In this paper we address the problem of ultrasound volume data segmentation by means of active contours. The segmentation is performed on an slicc-by-slice basis but exploiting the high correlation that exists across nearby slices. We have used active rays to alleviate the computational load of the optimization process. Classical energy functions have trouble finding the optimal solution in speckle imagery. We therefore propose new energy functions that work well under this type of images. Moreover, we propose both a probabilistic relaxation scheme and a heuristic search of the minimal energy configuration to end up making a hybrid use of both. We compare two rendered surfaces to illustrate the smoothness of our reconstruction. | URI: | http://hdl.handle.net/10553/76951 | ISBN: | 0-7803-6293-4 | ISSN: | 1520-6149 | DOI: | 10.1109/ICASSP.2000.859293 | Fuente: | ICASSP, IEEE International Conference on Acoustics, Speech and Signal Processing - Proceedings [ISSN 1520-6149], v. 4, p. 2274-2277, (Enero 2000) |
