摘要:

医学图像的分割是一个关键问题:许多分析和分类过程都依赖于此分割。随着越来越多的人出现背痛和相关问题,骨折椎体的自动或半自动分割成为一项具有挑战性的任务。一般来说,这些裂缝呈现出几个强度不均匀的区域,并且暗区域与附近的结构非常相似。为了克服这一挑战,在本文中,我们提出了一种半自动分割方法,称为平衡增长(BGrowth)。在102个破碎椎骨和89个正常椎骨的数据集上的实验结果表明,我们的方法显着优于文献中的知名方法。我们已经实现了高达95%的准确性,同时保持可接受的处理时间性能,这是相当于国家的最先进的方法。此外,BGrowth即使使用粗糙(草率)的手动注释(种子点)也能呈现最佳结果。

英文摘要:

Segmentation of medical images is a critical issue: several process of analysis and classification rely on this segmentation. With the growing number of people presenting back pain and problems related to it, the automatic or semi-automatic segmentation of fractured vertebral bodies became a challenging task. In general, those fractures present several regions with non-homogeneous intensities and the dark regions are quite similar to the structures nearby. Aimed at overriding this challenge, in this paper we present a semi-automatic segmentation method, called Balanced Growth (BGrowth). The experimental results on a dataset with 102 crushed and 89 normal vertebrae show that our approach significantly outperforms well-known methods from the literature. We have achieved an accuracy up to 95% while keeping acceptable processing time performance, that is equivalent to the state-of-the-artmethods. Moreover, BGrowth presents the best results even with a rough (sloppy) manual annotation (seed points).
