Résumé :

Image segmentation is a crucial task in the image processingfield. This paper presents a new region-based active contour whichhandles global information as well as local one. The trade-off betweenboth of these information is achieved by spatially varying function thatcontrols the moving and the stopping of the contours. The applicationof the method on computed tomography and X-ray images shows itseffectiveness to achieve a good object extraction. . .
