摘要： A two dimensional pattern such as a movement matrix generated in an inter-frame video coder is classified by forming a weighted sum modulo x of a set of values representing the pattern. The values may be pattern element values, or quantised representations of groups of elements. The weighted sum is used to access a look-up table containing class identification words. Optionally, motion vectors may be generated by comparing class identification words derived from successive frames of a picture.

摘要： A multiple font optical character recognition reader system for capturing character patterns by pixel, quantizing and sequencing the data representing multiple pixels, enhancing the character patterns represented by the data, locating characters within the enhanced data, and recognizing the characters. Data representing individual pixels is quantized into white, gray and black levels. During enhancement, gray pixel data is selectively changed to black or white while some black is changed to white, both operations depending on the white, gray or black levels in adjacent pixels. The enhanced data is scanned for a multiplicity of simultaneous conditions which define when a matrix of the data includes a character pattern which is optimally positioned within the matrix. The data matrix containing the character pattern is then sequentially compared to sets of data individually representing templates of potential characters. When optimal matching and threshold conditions are satisfied, a character is classified as recognized.

摘要： An apparatus for recognising unknown input patterns is described. The pattern to be recognised is converted into electrical signals representing, for example, the darkness or density of the picture elements forming the input pattern by units 1, 2, 4 and 4. The signals are stored in an input pattern memory 4. A basis generating unit 5 generates a plurality of orthonormalised vectors or bases from the stored input pattern, these are used to construct an input subspace of the input pattern. A reference pattern memory 8 stores reference patterns for a number of categories. These reference patterns vectors which are used to construct a reference subspace. A similarity value is defined as an angle 8 between the input subspace and the reference subspace. A matrix generating unit 7 and an eigenvalue calculating unit 10 are provided for measuring the angle e. The matrix generating unit 7 produces a matrix from the orthonormalised vectors generated by the basis generating unit 5 and the reference patterns stored in the reference memory 8. The maximum eigenvalue of the matrix calculated by eigenvalue calculating unit 10, corresponds to the angle 8. A decision unit 12 determines the category to which the input pattern belongs by comparing the eigenvalues representing the categories.

摘要： Coordinates of a handwritten pattern drawn on a tablet (100) are sequentially sampled by a pattern recognition unit (200) to prepare pattern coordinate data. Based on an area encircled by segments created by the sampled pattern coordinate data of one stroke and a line connecting a start point and an end point of the one-stroke coordinate data, the sampled pattern coordinate data of the one stroke is converted to straight line and/or curved line segments. The converted segments are quantized and normalized. The segments of the normalized input pattern are rearranged so that the input pattern is drawn in a predetermined sequence. Differences between direction angles for the rearranged segments are calculated. Those differences are compared with differences of the direction angles of the dictionary patterns read from a memory (300) to calculate a difference therebetween. The matching of the input pattern and the dictionary pattern is determined in accordance with the difference, If the matching fails, the first or last inputted segment of the input pattern is deleted or the sampled pattern coodinate data of the next stroke are added, to continue the recognition process.

摘要： The invention provides a pattern recognition apparatus and method by which an unknown input pattern is divided into a plurality of sub-area patterns matched with a plurality of standard partial characteristic patterns fo form an input pattern similarity matrix. The matrix is then matched with a plurality of reference similarity matrices of standard reference patterns, whereby the unknown pattern is recognized as one of standard reference patterns which gives the best matching. In the apparatus, digital signals corresponding to the sub-area patterns are supplied to a first similarity calculator (15) to which the partial characteristic patterns are supplied from a first dictionary memory (16). The calculator (15) calculates the input pattern similarity matrix. A second similarity calculator (19) calculates similarities between the input pattern similarity matrix and each of reference similarity matrices read out from a second dictionary memory (18). A comparator (20) identifies one reference pattern.
