摘要

人类视觉系统只能区分到二阶统计量的不同区域。很多恶性肿瘤都有肉眼看不见的边界。我们提出了一种算法，旨在通过计算数据的高阶统计量的梯度来揭示灰度图像中的“隐藏”边界。我们通过将其应用于识别可能的“隐藏”胶质瘤边界来证明它在MRI 3D扫描中表现出来。

3D non-linear invisible boundary detection filters

The human vision system can discriminate regions which differ up to the second order statistics only. A lot of malignant tumours have boundaries which are not visible to the human eye. We present an algorithm designed to reveal "hidden" boundaries in grey level images, by computing gradients in higher order statistics of the data. We demonstrate it by applying it to the identification of possible "hidden" boundaries of gliomas as manifest themselves in MRI 3D scans.
