Notes on ZeroThresholding of KH and KJ Sign Images

比较了ＫＨ符号图和ＫＪ符号图的零曲率阈值设置问题，指出ＫＨ零阈值相容不等式在ＫＪ情况下仍然适用，因此利用ＫＨ符号图作曲面分割实际上是一个更好的选择。

This paper compares the KH and KJ sign images in the context of the zerothresholding at single and multiple scales. A function in the real number field is given for implementing the transformation from the KH coordinate to the KJ coordinate. It is shown that the consistent zerothresholding inequality εK≥2εH+ε2H maintains effectiveness for both KH and KJ sign images. Therefore, from the viewpoint of zerothresholding, the KH sign image is virtually a better choice for surface segmentation.
