Abstract: A method for finding a predefined object in an image includes selecting a line belonging to the object, the line having a known stroke width and defining a maximum width (56) and a minimum width (58) that together define a range of widths (60) therebetween that contains the stroke width. A feature in the image is found having a feature width within the range, and the feature is processed to determine whether it is a part of the object.

Abstract: A method for calibrating a printer and/or a scanner so that information can be printed at a desired location with respect to a sheet, comprises: storing a first set of markings as a first image in digital form; printing the first image on a sheet to form a printed sheet; scanning the printed sheet to generate a second image stored in digital form; comparing the first image and the second image, or an image derived from the second image, to determine a first transformation which maps the first set of markings in the second image, or the image derived from the second image, onto the first set of markings on the first image; storing parameters of the first transformation for subsequent use by applying the first transformation to information to be printed at the desired location. Using this method the bias transformations associated with a printer and/or a scanner can be accurately measured and stored for future use in printing. The method finds particular application in a system for enabling the filling in of preprinted forms.

Abstract: Image processing apparatus is disclosed for splitting, for subsequent storage or processing by OCR apparatus, character images in digital form comprising connected characters, the image processing apparatus extracts an image skeleton from an input image and represents the topology of the image skeleton in a first data structure; generates, from the first data structure, second data structures representing the topologies of the results of possible splits of the input image skeleton; evaluates the second data structures and selects one of the possible splits to thereby split the input image.
