Palm Print Features for Personal Authentication Based On Seven Moments

Abstract

Biometric images are considered as one of the major coefficients in the field of personal authentication. One of the main approaches for personal identification is based on palm print. So studying the features extracted from palm print image adopted to get high efficient system for any recognition systems. In this research two major phases are hold on, in the first phase a database was built for 100 persons by acquiring four images for both hands (4 for left hand and 4 for right hand), then processed to extract ROI (region of interest) by looking for the palm centroid then a square area is fixed based on that centroid. The pre-process play an important step for stable features. Evaluation of the seven moments for each image (8 images) follow the preprocess then stored in the database file (so each person will have 56 values), this phase called personal database preparation. The second phase is the detection phase, which requires the same steps to get 56 values then go through the database looking for the closest person to the tested one. The system evaluation measured by statistical metrics which show good result goes up to 95.7% when applied on 50 persons with different conditions. Also the effect of ROI dimension with individual hands and integrated both of them studied, and the recommended dimension is 192*192.

Human Identification Based on SIFT Features of Hand Image

“…Palmprints are a unique biometric feature because of their characteristics, including good efficiency, maximum speed, ease of use, and relatively inexpensive. Palmprint recognition has gained a lot of care over the past decade [6], [7]. A small patch of the palm's texture is defined as a palmprint that contains more data that is helpful for personal authentication systems.…”
