A system and method for segmentation of structures in an image based on curvature slope are provided, the system including a processor, a curvature slope unit in signal communication with the processor for computing curvature slopes in the image and discarding voxels having a slope not satisfying specifications, and a segmentation unit in signal communication with the processor for locating connected clusters of retained voxels; and the method including computing curvature slopes in the image, discarding voxels having a slope not satisfying specifications, and locating connected clusters of retained voxels.
L'invention concerne un système et un procédé de segmentation de structures dans une image selon la pente d'une courbe. Le système comprend un processeur, une unité pente de courbe pouvant transmettre des signaux au processeur afin de calculer les pentes d'une courbe dans l'image, et d'écarter les voxels dont la pente ne répond pas à certaines spécifications ; et une unité segmentation pouvant transmettre des signaux au processeur afin de localiser les groupements reliés de voxels retenus. Le procédé comporte les étapes consistant à calculer des pentes de courbe dans l'image ; écarter les voxels dont la pente ne répond pas à certaines spécifications ; et localiser les groupements reliés de voxels retenus.
