abstract = "This work presents some preliminary results of the project
Analysis of Facial Profiles. The aim is to establish a method of
segmentation, description and classification of human facial
profiles. Special emphasis is given to the analysis of changes in
shape and the use of curvature variation along the profile.
Mathematical techniques for quantitatively describing the changes
produced by surgery have been developed, including methods of
automatic profile segmentation and curvature analysis using scale
space techniques. A medical graphics workstation is used for data
analysis, which generates a three-dimensional model of the facial
surface from data of CT, MRI scanners or from a custom built laser
scanner, allowing the definition and extraction of a number of
arbitrary sections (sets of x-y coordinate points). Mid-line
facial profiles representing the pre and post-treatment states of
a patient following surgery to the middle third of the face is
used to illustrate some of the methods.",
