More numerically accurate method for edge detection based on zero crossing of the second derivative in the gradient direction (SDGD) proposed by Marr D., Hildreth E.C. in 'Theory of edge Detection' In Proceedings of the Royal Society, 207, pp. 187-217, 1980.
This is a second try. After trying to update the original submission from 2005-12-01, the file just disappeared from the FEX
