摘要:

目前的图像分割技术通常需要用户调整几个参数,以获得最大的分割精度,计算效率低的方法,特别是当大量的图像必须在日常实践中顺序处理。最近提出了一种方法,根据专家用户的质量期望自动调整参数分割医学图像的进化模糊系统的使用(进化模糊图像分割EFIS)。然而,EFIS在实际应用中受到一些限制,主要是由于一些固定的参数。例如,EFIS依赖于自动检测感兴趣的对象进行特征计算,这是一项高度依赖于应用程序的任务。这一缺点限制了EFIS的适用性,EFIS的最终目标是提供一个通用但可调整的分割方案。在本文中,一个新版本的EFIS提出,以克服这些限制。新的EFIS,称为自配置EFIS(SC-EFIS),使用可用的训练数据,以自我估计的参数,固定在EFIS。同样,所提出的SC-EFIS依赖于不需要ROI的自动检测的特征选择过程。使用与EFIS相同的分割算法和相同的数据集对拟定的SC-EFIS进行评价。结果表明,SC-EFIS可以提供与EFIS相同的结果,但具有更高的自动化水平。

英文摘要:

Current image segmentation techniques usually require that the user tune several parameters in order to obtain maximum segmentation accuracy, a computationally inefficient approach, especially when a large number of images must be processed sequentially in daily practice. The use of evolving fuzzy systems for designing a method that automatically adjusts parameters to segment medical images according to the quality expectation of expert users has been proposed recently (Evolving fuzzy image segmentation EFIS). However, EFIS suffers from a few limitations when used in practice mainly due to some fixed parameters. For instance, EFIS depends on auto-detection of the object of interest for feature calculation, a task that is highly application-dependent. This shortcoming limits the applicability of EFIS, which was proposed with the ultimate goal of offering a generic but adjustable segmentation scheme. In this paper, a new version of EFIS is proposed to overcome these limitations. The new EFIS, called self-configuring EFIS (SC-EFIS), uses available training data to self-estimate the parameters that are fixed in EFIS. As well, the proposed SC-EFIS relies on a feature selection process that does not require auto-detection of an ROI. The proposed SC-EFIS was evaluated using the same segmentation algorithms and the same dataset as for EFIS. The results show that SC-EFIS can provide the same results as EFIS but with a higher level of automation.
