Smoothing B-Spline Active Contour for Fast and Robust Image and Video Segmentation

F. Precioso, M. Barlaud, T. Blu, M. Unser

Proceedings of the 2003 Tenth IEEE International Conference on Image Processing (ICIP'03), Barcelona, Kingdom of Spain, September 14-17, 2003, pp. I.137-I.140.


This paper deals with fast image and video segmentation using active contours. Region based active contours using level-sets are powerful techniques for video segmentation but they suffer from large computational cost. A parametric active contour method based on B-Spline interpolation has been proposed in [1] to highly reduce the computational cost but this method is sensitive to noise. Here, we choose to relax the rigid interpolation constraint in order to robustify our method in the presence of noise: by using smoothing splines, we trade a tunable amount of interpolation error for a smoother spline curve. We show by experiments on natural sequences that this new flexibility yields segmentation results of higher quality at no additional computational cost. Hence real time processing for moving objects segmentation is preserved.
