Abstract

See full text

A method detecting a rectangle enclosed by a pair of parallel horizontal lines that are demarcation lines between the palm pattern impression and the background in wrist-side and fingertip-side, and a pair of parallel vertical lines are orthogonal to the horizontal lines and are demarcation lines between the palm pattern impression and the background in thumb-side and little-finger-side. The method splits the rectangle into, three segments horizontally by four segments vertically, and then splits the palm pattern impression into three regions, the first being a combination of three segments horizontally by two segments vertically located toward the fingertip among the segments, the second being a combination of two segments horizontally by three segments vertically located toward the thumb and the wrist among the segments, and the third region being a combination of two segments horizontally by three segments vertically located toward the little finger and the wrist among the segments.
