From Step Edge to Line Edge: Combining Geometric and Photometric Information

As a Gradient rlctector produces two extrema when applird t,o a line, we propose an original method which is bawd on sr~cll a detector but which appropriately rcs-ponds to both step and line eclges. The idras are first to ident,ify line contours using geometric and phot,omctric propcrt,ics and second to s~tbsti tute a line for a single cont.oi~r using… CONTINUE READING
