Region-based active contour with adaptiveB-spline. Application in radiographic weldinspection

Result of segmentation using Active Contours based on Splines using good initialization: (left) original image, (middle) evolution of spline.. curves, (right) the

The radical scavenging capacity (RSC) of all lignin samples was tested towards DPPH • and ABTS •+ in absolute ethanol and water with- out cellulose by measuring the EC50 sol

The proposed split and merge strategy on the spline model consists in: adding a new control point when CSL is greater than a certain splitting threshold so that the contour tracks

With the advances in computer science and artificial intelligence techniques, the opportunity to develop computer aided technique for radiographic inspection

In this approach we exploit the performance of the GVF as external force and enhance it by joining to it external adaptive pressure forces which bring speed to the snake evolution
