The neuroanatomical morphology of the optic nerve is an important description for understanding different aspects like topological distribution of nerves. Manual identification and morphometry has been usually considered as tedious, time consuming, and susceptible to error. A method that automates the identification and analysis of axons from electron(More)
A suture simulation system is developed. Using a Phantom desktop haptic device, user can insert a virtual needle into a deformable object and pull a virtual suture attached to the needle through the object. The object can deform under the interaction of both the needle and the suture. The suture uses rigid link model and FTL(Follow the Leader) deformation(More)
OTSU method is considered to be the best algorithm for image segmentation of threshold selection. It's very simple and it's regardless of image brightness and contrast effects. Therefore it has been widely used in digital image processing. However, in the actual image, because of the influence of noise etc., traditional OTSU algorithm cannot be obtained an(More)
Grid computing is a hot research direction in computer field. Resource management is an important part of this research. In Grid environment, satisfactory services for discovering resources and allocating appropriate resources can be provided to the Grid users though the agents. Agent based resource management with alternate solution (ABRMAS) has been(More)
Independent Component Analysis (ICA) has found its application in face recognition successfully. The goals are to estimate the components from raw image data. These components are then used to extract features of face images on which face classification is conducted. The components play key role in face recognition system. However these separated components(More)
A second order Mumford-Shah model is proposed for image denoising. Unlike the original Mumford-Shah model, the proposed new model uses second order derivatives defined in bounded Hessian space as its regulariser. This model is capable of eliminating the undesirable staircase effect associated with the original Mumford-Shah model with a total variation(More)
A novel multiphase image segmentation model under variational level set method framework is presented in this paper. The energy functional includes three parts: the first one is region-based component resulted from maximum a posterior probability of image partition, the second one is based on minimum geodesic active contours, the third one comes from the(More)
