{IMAGE CONTOURING AND COMPARING}
Bruce G. Baumgart
ABSTRACT:
A contour image representation is stated and an algorithm
for converting a set of digital television images into this
representation is explained. The algorithm consists of five steps:
digital image thresholding, binary image contouring, polygon
nesting, polygon smoothing, and polygon comparing. An
implementation of the algorithm is the main routine of a program
called CRE; auxiliary routines provide cart and turn table control,
TV camera input, image display, and xerox printer output. A
serendip application of CRE to type font contruction is explained.
Details about the intended application of CRE to the perception of
physical objects will appear in sequels to this paper.
