Very good reading, indeed. Then, add to the Marr-Hildreth and Canny optimal
edge detectors;

J. Shen, S. Castan, "An Optimal Linear Operator for Step Edge Detection,"
CVGIP: Graphics Models and Image Processing, vol. 54, No. 2, March
1992, pp. 112-133.

But, for God's sake, before developing any new (optimal or not) edge
detectors, read please:

R. C. Jain, T. O. Binford, "Ignorance, Myopia and Naivete in Computer
Vision Systems," CVGIP: Image Understanding, vol. 53, No. 1, Jan.
1991, pp. 112-117, 1991.

Recognition Letters vol. 13, April 1992, pp. 221-225.
