Contourlet-based active contour model for PET image segmentation.
PURPOSE PET-guided radiation therapy treatment planning, clinical diagnosis, assessment of tumor growth, and therapy response rely on the accurate delineation of the tumor volume and quantification of tracer uptake. Most PET image segmentation techniques proposed thus far are suboptimal in the presence of heterogeneity of tracer uptake within the lesion. This work presents an active contour mod...
متن کاملGlobal-Statistics-Based Active Contour Model for Image Segmentation
This paper presents a localand global-statistics-based active contour model for image segmentation by applying the globally convex segmentation method. We first propose a convex energy functional with a local-Gaussian-distribution-fitting termwith spatially varyingmeans and variances and an auxiliary global-intensity-fitting term. A weight function that varies dynamically with the location of t...
متن کاملAn efficient Self-Organizing Active Contour model for image segmentation
Active Contour Models (ACMs) constitute a powerful energy-based minimization framework for image segmentation, based on the evolution of an active contour. Among ACMs, supervised ACMs are able to exploit the information extracted from supervised examples to guide the contour evolution. However, their applicability is limited by the accuracy of the probability models they use. As a consequence, ...
متن کاملDirectional geodesic active contour for image segmentation
By incorporating the image gradient directional information into the geodesic active contour model, we propose a novel active contour model called directional geodesic active contour, which has the advantage of selectively detecting the image edges with different gradient directions. The experiment results show the high performance of the proposed active contour in image segmentation, especiall...
متن کاملConstrained Active Contour For Interactive Image Segmentation
Interactive image segmentation algortihms incorporates small amount of user interaction to define the desired content to be extracted, has received much attention in the recent years. We propose a robust and accurate interactive method based on the recently developed continuous-domain convex active contour model. The proposed method exhibits many desirable properties of an effective interactive...
