摘要: 主动轮廓模型是进行图像分割的有效方法,但主动轮廓模型在确定初始轮廓方面主要靠经验,理论方法不多。为此,提出了一种基于改进骨架算法的主动轮廓模型进行图像分割的方法。首先利用改进的骨架算法和轮廓重生算法,生成初始轮廓;再利用含有形状能量的主动轮廓模型进行轮廓的演化,使其接近真实的目标边缘,获得期望的图像分割结果。实例验证和比对实验结果表明,与传统的主动轮廓模型相比,该方法在图像分割的准确性和抗噪性方面有很大的提升。

Abstract: Active contour model is an effective image segmentation method,but there aren’t many methods in the active contour model when determing the initial contour.In such case,this article put forward an improved skeleton extraction algorithm based active contour model to solve the problem.The model creates an initial contour by improved skeleton extraction algorithm and contour repossession algorithm,then evolves the contour towards true edge of object by the active contour model with shape energy item,to achieve the expected image segmentation.The example verification and comparision experiment prove the model can segment out the object area from the image in a much better way,with good noise immunity.Compared with traditional active contour,the model has a great improvement in segmentation accuracy.
