A Fourier-based implicit evolution scheme for active surfaces, for object segmentation in volumetric images
(2013)Active contours (AC) and active surfaces (AS) have been used extensively for segmentation and measurement in two- and three-dimensional images. The small time steps used in discretizing the evolution equation of AC/AS with ... -
An implicit evolution scheme for active contours and surfaces based on IIR filtering
(2014)In this work, we present an approach for implementing an implicit scheme for the numerical solution of the partial differential equation of the evolution of an active contour/surface. The proposed scheme is applicable to ... -
An intelligent tool for anatomical object segmentation using deformable surfaces
(2012)Image segmentation is a very active area of research in machine vision. In this work, an innovative methodology is presented that allows the segmentation of objects in three-dimensional images with initial user intervention. ... -
A novel tool for segmenting 3D medical images based on generalized cylinders and active surfaces
(2013)Three-dimensional (3D) medical imaging has been incorporated in routine clinical practice, since the required infrastructure has become increasingly affordable. New algorithms and applications are needed to serve the ...
