ABSTRACT:
The present invention provides an image pattern identification/recognition method which enables the reduction of the work load of the user required in the case of incorrect character recognition, as well as facilitating the addition of a new recognition pattern in the dictionary so that the pattern can be identified and added thereafter. A binary image pattern which has been entered is compared to each of the binary mask patterns prepared in advance for each of the recognition categories so as to identify/recognize the binary pattern and to determine the recognition category to which the binary pattern belongs. The binary image pattern is identified as belonging to the first recognition category if the black portions of the binary image pattern are contained in the black portions of the binary mask pattern of the first recognition category and if the black portions of the binary image pattern are contained only in the double black portions between the binary mask pattern of the first recognition category and that of the second recognition category.
