[Geometric active contour model with color and intensity priors for medical image segmentation].

A new algorithm using the geometric active contour model with the fusion of color and intensity priors to segment medical images is presented in this paper. The prior knowledge used here are firstly defined in different color spaces and represented as thresholds searched by the genetic algorithm. Then the prior knowledge is merged into active contour model with its contour evolution by the level set technique. The experiments on clinical marrow images and mammograms have successfully demonstrated its superiority of the proposed algorithm over the existing active contour models which deal with image gradient information.

[Research progresses on deformable model in medical image processing].

In recent years, image processing technique based on deformable models has been widely used in the field of medical image processing and analysis. This survey demonstrates the principle of two kinds of basic deformable models, i.e. parametric deformable model and geometric deformable model. The design of model in application is also discussed. By incorporating prior knowledge and modeling global properties, several new extensions of basic deformable model are then reviewed. At last, some prospects of possible research are given.
