Abstract: A fuzzy method for the recognition of geometric shapes in images, the particularity whereof is that it comprises the following steps: recognition of at least one edge of a curve of an image; recognition of the gradient of the edge; correction of the gradient by virtue of first fuzzy means; and determination of the number of points that belong to the curve by virtue of second fuzzy means. The process according to the present invention is performed by a fuzzy device for the recognition of geometric shapes in images that comprises: an edge detector, adapted to recognize at least one edge of a curve of an image and adapted to recognize the gradient of the edge; a fuzzy gradient corrector, adapted to correct said gradient; a fuzzy vote attributor, adapted to determine the number of points that belong to the curve.
