摘要： A character recognition method includes a step of assigning one of a plurality of predetermined directionality codes to each of the pixels defining the contour of a character pattern. Then, the character pattern, to which the directionality codes have been assigned, is subdivided into a plurality of mesh regions. In this case, in accordance with the present invention, the character pattern is not directly subdivided into mesh regions, and, instead, the character pattern is first subdivided into a first plurality of sub-regions and then the first plurality of sub-regions are converted into a second plurality, which is smaller in number than the first plurality, of mesh regions by combining at least some of said first plurality of sub-regions. Such a two-step subdivision process of a character pattern is advantageous in absorbing fluctuations caused by modifications of the character pattern, such as hand-written characters.

摘要： A circumscribing rectangle is obtained for a black continuous image part using a two-tone image signal. If it is determined that the image part is possibly one which is obtained as a result of rotating the object, lengths of sides of the image part are compared with threshold values. If it is determined that the image part is not one which is obtained as a result of rotating the object, the height and horizontal length of the circumscribing rectangle are compared with the threshold values. Thus, it is determined whether or not the image part is identical to the object. An RGB chromaticity histogram is produced for each of small regions of an input color image. Each of the chromaticity histograms of the small regions is compared with reference ones. As a result of the comparison, an identification number of the reference histogram having the highest similarity to that of the small region among those constituting the input image is given to the small region. A histogram of the identification numbers thus is produced for the input color image. The thus-produced histogram is used to determine which one of a plurality of objects is identical to the input color image.

摘要： A binarization method obtains an optimum threshold value for binarization which is used when converting a multi-level image data which describes an input image into a black-and-white bi-level image data. The binarization method includes the steps of counting a first number of black picture elements by varying a threshold value from a darkest tone level to a lightest tone level, counting a second number of picture elements having a tone level other than the lightest tone level, obtaining a percentage of the first number with respect to the second number for each of the varied threshold values so as to normalize a density of the input image, and determining the optimum threshold value for binarization based on the percentage which is obtained for each of the varied threshold values.
