Sentence examples for evolution contour from inspiring English sources

(c) An automatic initialization method based on the vessel shape enhancement is developed, and it can provide a good initial evolution contour that makes the model converge rapidly, which avoids repeated trails in conventional local region active contour models.

Thirdly, an automatic initialization method for the evolution contour was developed by vessel shape enhancement, which overcame the problem of repeated trials for the initial contour of conventional local region active contour models for vessel segmentation and made the model converge rapidly.

The final step is to perform the evolution itself (contour evolution module).

The paradigm of the level set is a numerical method for tracking the evolution of contours and surfaces.

A recent model for active contours based on the techniques of curve evolution considers blurred contours as contours which are not necessarily defined by gradient.

The external potential is now in charge of the guidance of the contour evolution and the internal potential prevents the evolution through small cavities or discontinuities in the vessels topology.

Finally, the regularization term ensures the stability of contour evolution.

Second, an open source graphically interactive 3D segmentation tool based on the aforementioned contour evolution is implemented and is publicly available for end users on multiple platforms.

where is a coefficient controlling the speed of evolution of the contour including the constants and.

If it is less than a convergence threshold t, the active contour evolution will be stopped.

After having obtained the models, object silhouettes are tracked by using shape matching or contour evolution.
