Straight lines in a compensated image of a wide-angle image are identified (102) and corresponding curved lines of pixels in the wide-angle image identified (103) as well. For given points in the aforementioned straight lines, a corresponding point in the corresponding curved lines is identified by determining an intersection of those curved lines with another line of pixels in the wide-angle image (104). The latter can comprise either a curved line that corresponds to another straight line in the compensated image, in which case the intersection is noted by tracing the curved lines using a scan-rasterization algorithm. The latter can also comprise, if desired, a straight line that corresponds to another straight line in the compensated image. In either case, the point of intersection is readily and efficiently determined.
