A theory for describing and measuring the concavities of cellular complexes (digitized silhouettes) is developed. This theory involves the use of the minimum-perimeter polygon and its convex hull.
Artificial retina, cellular convexity, digitization of pictures, image processing by computer, minimum-perimeter polygon, pattern recognition, shape analysis, smoothing of silhouettes.
