Lankton S, Tannenbaum A. Localizing region-based active contours. IEEE transactions on image processing. 2008 17(11):2029-2039 Localizing Region-Based Level-set Contouring for Common Carotid Artery in Ultrasonography Yong Chen*, Xiao Ming Zhou, Dong C Liu School of In this work, we proposed to use local region-based active contours introduced by [8] to extract the lumen-intima-boundary (LIB) from Ultrasound images. Conventional method of region-based active contour model adopts the global information of image and is unable to perform well. In this paper, from a localized perspective, we introduce the methodology of localized active contour model (LACM) and, meanwhile, propose the method that using LACM to A Tutorial on Active Contours. Figure 2: A curve can be implicitly dened as a level set of a surface. Such representation of curve C is advantageous since it is independent of parametrization A Tutorial on Active Contours. One can simply work this out and get the well-known equation for curvature of. A Tutorial on Active Contours. Figure 2: A curve can be implicitly dened as a level set of a surface.

This thesis presents an alternative The data term, inspired from the region-based active contour approach proposed by Chan and Vese, evolves the contour relied In this paper, by employing the cosine function to express the so-called data fitting term in traditional active contour models, we propose an active contour After that, in order to segment the image with intensity inhomogeneity, we extend the proposed global model to the local cosine fitting energy.
