In this paper, we propose a novel model for simultaneous image segmentation and object recognition. Our model is different from previous prior-based level set variatioinal image segmentation in two aspects. The first is the use of the shape sparse representation, which is able to integrate shape priors by linear combination into variational image segmentation. The second is that segmentation and recognition...
Global shape prior knowledge is a special kind of semantic information that can be incorporated into an image segmentation process to handle the difficulties caused by such problems as occlusion, cluttering, noise, and/or low contrast boundaries. In this work, we propose a global shape prior representation and incorporate it into a level set based image segmentation framework. This global shape prior...
A top-down image segmentation method is proposed in this paper, utilizing level set image representation and the piecewise-constant Mumford-Shah functional. The method achieves top-down hierarchical segmentation by taking advantage of the tree structure provided by level set image representation. The piecewise-constant Mumford-Shah functional is utilized in the proposed method to determine if each...
The global shape prior knowledge has been exploited by many image segmentation approaches in order to improve segmentation results when there are such problems as occlusion, cluttering, low contrast edges, etc. We propose a global shape prior representation and incorporate it into a level set based segmentation framework. This global shape prior can effectively help remove the cluttered elongate structures...
In this work, we introduce a novel implicit representation of shape which is based on assigning to each pixel a probability that this pixel is inside the shape. This probabilistic representation of shape resolves two important drawbacks of alternative implicit shape representations such as the level set method: Firstly, the space of shapes is convex in the sense that arbitrary convex combinations...
