Liver segmentation in MR Image is the first step of our automated liver perfusion analysis project. Traditional Level Set methods and active contours were often used to segment the liver, but the results were not always promising due to noise and the low gradient response on the liver boundary. In this paper we propose a novel level set based variational(More)
Liver segmentation in MR Image is the foundational work for further research in our lab. Traditional Level Set methods and active contours were often used to segment the liver, but the results were not always promising due to noise and the low gradient response on the liver boundary. In this paper we propose a novel level set based variational approach that(More)
Given the fact of failure of PCB detection and diagnosis equipment for a type of ballistic missile in locating faulty component, PCB detection and diagnosis system for a type of ballistic missile is developed by integrating such technologies as microprocessor-based testing technology, fault diagnosis technology and embedded technology to realize accurate(More)
The vertebrae registration is very important to treat the vertebrae diseases. As the vertebrae has rigid bones and soft tissue, the traditional nonrigid registration canpsilat work well on that. In this paper, a novel multi-stage nonrigid registration with rigid constraint to the vertebrae is presented. Firstly, A new rigid transform constraint is(More)
