abstract = {This paper reports on experiments in detecting face
contours from front-view ID-type pictures. Based on the eye and mouth
positions, which can be detected by the algorithms proposed in [5], a
simplified Adaptive Hough Transform (AHT) technique is used to identify
approximately vertical straight lines of the cheeks from the edge
image. Independently, parabolas forming the chin are detected by
another AHT procedure. The location and curvature of the chin line,
together with the cheek lines, characterize the shape of the face. This
method was tested on over 70 different face images and is shown to
produce results with a high degree of accuracy. We discuss in detail
the specific issues involved in the detections, such as the definition
of relevant subimage, parameter ranges, resolution of the accumulator
array, peak cells, and end point determination.},
