Full field surface data of cylindrically shaped objects, such as a human's head, can be acquired by rotating a triangulated laser and imaging system about the subject. The method of acquisition is imperfect and requires post processing of the data obtained. To eliminate rough or irregular surface data, a two-dimensional convolution can be used. To eliminate spikes or impulse noise in the data, morphological filters are available. Proper use of both operations requires knowing and understanding the operational parameters. This paper presents an overview of these methods and discusses the optimal parameter settings as have been determined by experimentation.
