Application of genetic algorithms to construction of immune-based detector / 医疗卫生装备

In recent years,immune-based intrusion detection has become a key research in computer security area,which has opened up a new conjecture for computer security.Genetic algorithms,which simulates the natural evolution,can optimize the searching process.Based on natural immune theory,this research simulates natural cognition and memory mechanism to form and analyze an algorithm of constructing detector.

Survey of Medical Image Segmentation Based on Deformable Models / 医疗卫生装备

The classical deformable models and some new approaches for the past few years are surveyed,especially de-scribe two important methods of them: snake model and level-set model.Image segmentation is the bases of 3D recon-struction technology and medical visualization image,which are meaningful to disease diagnosis and therapy in clinical.It is not only a key step and critical technology in medical image processing and image analysis but also a classic puzzle.With the need of application,it is very important to continually research the image segmentation,to increasingly improve the old approaches and introduce the new and more effective ones.
