摘要:

A method for the computation of moments up to the third order of a binary image or blob encoded in crack code is presented. The method uses the projections of the blob on lines at 0, π/4, π/2 and 3π/4, introduces no approximations, and substantially reduces the computational effort compared with other methods.
