Claim 8:
9. A method comprising:
decomposing, by a processor, an image into a plurality of rows and a plurality of columns;
for each row of the plurality of rows, generating, by the processor, row data that identifies first values of the image at positions on the image corresponding to locations across the row;
for each column of the plurality of columns, generating, by the processor, column data that identifies first values of the image at positions, the positions on the image corresponding to locations across the column;
determining, by the processor, from the generated row and column data, second values at intersections of the plurality of rows and the plurality of columns, the second values corresponding to the edge representations;
generating, by the processor, a map that approximates non-flat portions of the image based on the determined second values; and
determining, by the processor, from the generated map, a two-dimensional array of points that samples edge representations of the image.
