摘要:

不对称分析的基础上重叠的热图像证明能够检测炎症和预测足部溃疡。该技术包括三个主要步骤:分割、几何变换和重叠。然而,重叠技术,其中包括从左脚的强度水平减去右脚的强度水平,如果左脚和右脚的投影不相同,也可以检测到假的异常区域。在本文中,我们提出了一种替代技术,以不对称分析为基础的重叠。所提出的技术,可扩展扫描,允许有效的比较,即使脚的形状和大小的投影出现在图像中不同。测试结果表明,基于不对称分析的可扩展扫描比基于不对称分析的重叠提供更少的虚假异常区域。

英文摘要:

Asymmetry analysis based on the overlapping of thermal images proved able to detect inflammation and, predict foot ulceration. This technique involves three main steps: segmentation, geometric transformation, and overlapping. However, the overlapping technique, which consists of subtracting the intensity levels of the right foot from those of the left foot, can also detect false abnormal areas if the projections of the left and right feet are not the same. In this paper, we present an alternative technique to asymmetry analysis-based overlapping. The proposed technique, scalable scanning, allows for an effective comparison even if the shapes and sizes of the feet projections appear differently in the image. The tested results show that asymmetry analysis- based scalable scanning provides fewer false abnormal areas than does asymmetry analysis -based overlapping.
