Extraction of Index, Middle, and Ring Finger Characteristics and Their Identification

In this study, a new technique is used to extract the index, middle and ring finger outlines. The orientations and geometrical features of these outlines are calculated and compared to identify different individuals. The techniques of database SQL searching and manipulation, image dilation, object position locating, image shifting, rotation, and interpolation are used to recognize different individuals. The hand was fixed each time when a photograph was taken, and one can assume that each time when a hand was acquired, the image was the same as the previous one. Since the photographs are the same, after the index, middle or ring fingers have been extracted from the hand image, the acquired images can be used to identify different persons.
