A method of detecting a geometrically transformed object in an image comprises comparing a template comprising a plurality of line segments for the object with regions of an image, and determining a similarity measure that uses a statistical measure based on the sums of pixel values of line segments of the image corresponding to each of the line segments of the template. Embodiments of the invention use a discrete set of geometrically transformed versions of the template, for example using the similarity transform. |
