METHOD AND APPARATUS FOR RECOGNIZING HANDWRITTENCHARACTERS IN AN OPTICAL CHARACTER RECOGNITION MACHINEABSTRACT OF THE DISCLOSUREHandwritten character recognition is facilitated inan optical character recognition machine by electronicallyscaling-down the size of received characters, both in heightand width, to normalized dimensions. The scaling-down factorsare rendered adjustable as a function of the dimensions of thereceived character. Actual recognition is rendered highlyreliable by employing a time-shared electronic mask whichtests the received characters for the following features, insequence: Top horizontal line; upper left and/or upper rightportion line crossings; mid-portion horizontal lines; lowerleft and/or lower right portion line crossings; and bottomhorizontal line. Recognition of the character is effected bydecoding the test results.
