Claim 1:
2. The apparatus of claim 1, wherein to determine the displacement values of the various locations, the instructions are further to cause the processor to:
decompose the image into a plurality of lines, wherein each of the plurality of lines intersects with a plurality of other lines in the plurality of lines;
for each line in the plurality of lines, generate line data that identifies first values at positions on the image, the positions corresponding to locations across the line;
determine, from the generated line data, second values at intersections of the plurality of lines, the second values differing from the first values and corresponding to the edge representations in the image; and
based on the determined second values, generate a map that approximates non-flat portions of the image.
