Abstract: An apparatus is disclosed for processing a raster image comprising a plurality of pixels. The apparatus comprises a computer readable medium for storing steps of a computer program, and a computer processor connected to the computer readable medium for executing the steps of the computer program. A plurality of borders of a first blob in the raster image are identified, and a plurality of borders of a second blob in the raster image are identified. The first blob is compared to the second blob, and when the first blob substantially matches the second blob, a first cluster representing both the first blob and the second blob is generated.

Abstract: A method and apparatus is disclosed for converting raster images into a vector format by identifying and converting the borders of image features into a mathematical format referred to as string sequences. To enable the string sequencing of color images, the present invention identifies and resolves contrast conflicts in the image features in order to avoid misperceiving the vectorized image when converted back into a raster format. A contrast conflict occurs when there is a “contrast tie” between overlapping features of the image. The feature that would normally be perceived as the dominant feature breaks the contrast tie so that when the vector image is reconstructed, the dominate feature appears in the foreground of the image while the recessive feature appears in the background.

Abstract: An apparatus is disclosed for converting a raster image comprising a plurality of pixels into a plurality of data tags representing at least one shape in the raster image.

Abstract: An apparatus is disclosed for defining non-axial line surfaces in border string sequences representing a raster image.

Abstract: Disclosed is a method and apparatus for converting the color borders of a raster image into a more abstract mathematical representation that can be converted into a vector format without significantly fragmenting the image. The invention involves scanning a neighborhood of cells in the form of a square matrix through the raster image in order to generate a surface string (or an indicia thereof) representing the color border at each pixel, and then to sequence the surface strings into string sequences which represent the color borders. By assigning color values to the neighborhood of cells that indicate whether the perimeter cells are the same or different in color than the center cell, the present invention is capable of defining color borders in raster images comprising three or more colors (as opposed to black and white images). The string sequences are generated by sequencing together string IDs rather than simple slopes which provides optimal information for generating vectors.

Abstract: An apparatus is disclosed for converting a raster image comprising a plurality of pixels into a plurality of data tags representing at least one shape in the raster image. The apparatus comprises a computer program, or an integrated circuit implementing the steps of the computer program, wherein the computer program comprises: (a) a border definer for generating a border string sequence representing a color border in the raster image, wherein: (b) the border string sequence comprises a plurality of surface strings; and (c) a surface string comprises a receive slope and a send slope representing a slope of the border passing through a predetermined area of the raster image; and (d) a surface string sequencer for converting the border string sequence into one or more surfaces, wherein a surface comprises one or more surface string sequences representing a section of the border string sequence.
