Abstract
To detect the presence of a logo in a search image, the positions of edges, in an image of the logo and in the search image, are represented by ratios of distances between the respective edge and a plurality of preceding edges. This can be carried out both horizontally and vertically. A sequence of edges at a selected position in the logo image is then compared with sequences of edges from a plurality of positions in the search image, and the position of the logo in the search image is determined from the position of a match between the respective sequences of edges.
