Filed: 1983-10-19
Abstract: PURPOSE:To improve the recognition speed by calculating and storing preliminarily lengths between standard patterns and obtaining the difference between the lengths and a calculated length to estimate a lower limit value of lengths between an input pattern and standard patterns. CONSTITUTION:Input patterns are inputted successively, and a length calculation object flag is set to ''1''. If this flag is ''0'', length calculation is omitted. If the flag is ''1'', length calculation is executed, and a lower limit value of lengths to left standard patterns is calculated on a basis of the calculated length and preliminarily calculated and stored lengths between standard patterns. If this lower limit value is larger than the value of the calculated length, the length calculation object flag for the next standard pattern is set to ''0''. Thus, the number of length calculation objects is reduced according as length calculation is performed, thereby reducing considerably the quantity of length calculation.
