I have a question about finding the symmetry plane that separate the left and the right halves of a point cloud. We scanned an object, say a human face, with a 3D scanner, such as Kinect, which gives a 3D point cloud. Now we want to find the plane that segments the face into symmetrical left and right halves. I found a paper like https://hal.inria.fr/file/index/docid/331758/filename/cvpr2008CombesFinal.pdf, but could not find any code. Though I found the C++ code "CLARCS" doing this work, but it is no longer available. Thank you.
