چکیده
Due to the low contrast, blurred boundary and intensity inhomogeneity of images, accurate segmentation breast cancer lesions with dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) still has great challenges. This paper proposed an improved active contour model (ACM) for segmenting in DCE-MRI images. First, based on extreme learning machine (ELM) method, a robust function is that combines image intensities time-domain features enhance difference between other tissues. Second, edge-stop (ESF) introduced by combining intensity, feature, Hessian shape index detect irregular boundaries. At lesions, energy ACM minimized evolution curve completes, so lesion region can be segmented. The mean Dice similar coefficient (DICE), Jaccard similarity (JC) Hausdorff distance (HD) 50 samples are 85.88±6.62%, 75.72±9.68% 11.62±4.72 mm, respectively. results segmented more manual than compared models.

Active-Contour-Based Image Segmentation Using Machine Learning Techniques
We introduce a non-linear shape prior for the deformable model framework that we learn from a set of shape samples using recent manifold learning techniques. We model a category of shapes as a finite dimensional manifold which we approximate using Diffusion maps. Our method computes a Delaunay triangulation of the reduced space, considered as Euclidean, and uses the resulting space partition to...
متن کاملBuilding Segmentation using an Active Contour Model
This paper addresses the problem of building detection in high-resolution (1m) images and proposes an Active Contour Model as one of the solutions to ease the problem. In building segmentation, it is important to identify approximated building regions, i.e., the regions where buildings are likely to exist. Once the approximated building regions are identified, the problem of building extraction...

Animal biometrics is a challenging task. In the literature, many algorithms have been used, e.g. penguin chest recognition, elephant ears recognition and leopard stripes pattern recognition, but to use technology to a large extent in this area of research, still a lot of work has to be done. One important target in animal biometrics is to automate the segmentation process, so in this paper we p...
