1 I. SUPPLEMENTARY NOTES

    A method is presented for the visual analysis of objects by computer. It
is particularly well suited for opaque objects with smoothly curved surfaces.

The method extracts information about ,the object:'^ surface properties, including measures of its specularity, texture, and regularity. It also aids i n determining the object's shape.

    The application of this method t o a simple recognition task -- the recognition o f f r u i t -- i s discussed. The results on a more complex smoothly curved object,
a human face, are also considered.

COMPUTER ANALYSIS OF VISUAL PROPERTIES OF CURVED OBJECTS;\

Abstract

    A method i s presented for the visual analysis of objects by computer. It is particularly well suited for opaque objects with smoothly curved surfaces. The method extracts information about the object" surface properties, including measures of its specularity, textur'e, and regularity. I t also ,aids in determining the object's shape.

    The application of this method to a simple recog- nition task -- the recognition of fruit -- i s discussed. The results on a more complex smoothly curved object, a human face, are also considered.

*This report reproduces a thesis of the same t i t l e submitted to the Department of Electrical Engineering, Massachusetts Institute of Technology, in partial fulfillment of the re- quirem'ents for the degree of Doctor of Philosophy, June 1970.
