surface_distance

Code for calculating mean absolute surface distance between two faces in T1w MRI images.

./v1 contains the original code used in the paper. ./v2 contains an updated version which improves mesh manipulation and adds visualization for quality control.

QA image for surface distance calculation by v2 QA image provided by v2

If any part of the code is useful for your research, please consider citing the following paper:
