局部熵驱动区域主动轮廓的局部化框架
Localizing Framework of Region-based Active Contours Driven by Local Entropy
摘要
Abstract
This paper proposes a framework which allows any region-based active contours can be re-formulated in a local way.The energy function of this framework consists of a geometric regularization term that penalizes the length of region boundaries and a data fitting term in a local region.It uses a slide window function to extract the local entropy according to the relationship of spatial arrangements of image pixel, which can map intensity space of image to local entropy space.Another window function can be used to extract local region information so that getting the localizing region-based active contours framework.It takes CV model as an example to demonstrate it.The analysis and comparison of the two familiar window functions also can be done.Experimental results for images illustrate that this model can segment the cluttered images.关键词
