چکیده

When segmenting three-dimensional medical data using level sets, re-distancing the implicit surface is time-consuming. We propose a fast implementation, based on Chamfer distance, which preserves the interface location. Experiments using synthetic and real data show reasonable accuracy and considerable speed-up. 2005 Elsevier B.V. All rights reserved.

Fast sub-voxel re-initialization of the distance map for level set methods

Re-distancing the implicit surface is time-consuming. We propose a fast implementation of the Chamfer distance which maintains the sub-voxel accuracy of the interface. This approximation to the Euclidean distance gives a reasonable accuracy while improving considerably the computation time.

A consistent solution of the reinitialization equation in the conservative level-set method

In this paper, a new re-initialization method for the conservative level-set function is put forward. First, it has been shown that the re-initialization and advection equations of the conservative level-set function are mathematically equivalent to the re-initialization and advection equations of the localized signed distance function. Next, a new discretization for the spatial derivatives of ...

An Efficient Algorithm for Level Set Method Preserving Distance Function

The level set method [1] is a popular technique for tracking moving interfaces in several disciplines including computer vision and fluid dynamics. However, despite its high flexibility, the original level set method is limited by two important numerical issues. Firstly, the level set method does not implicitly preserve the level set function as a distance function, which is necessary to estima...

The Time Adaptive Self Organizing Map for Distribution Estimation

The feature map represented by the set of weight vectors of the basic SOM (Self-Organizing Map) provides a good approximation to the input space from which the sample vectors come. But the timedecreasing learning rate and neighborhood function of the basic SOM algorithm reduce its capability to adapt weights for a varied environment. In dealing with non-stationary input distributions and changi...

Receptive Field Encoding Model for Dynamic Natural Vision

Introduction: Encoding models are used to predict human brain activity in response to sensory stimuli. The purpose of these models is to explain how sensory information represent in the brain. Convolutional neural networks trained by images are capable of encoding magnetic resonance imaging data of humans viewing natural images. Considering the hemodynamic response function, these networks are ...
