+# Introduction
+MMCBNU_6000 consists of finger vein images from 100 volunteers. Each subject was asked to provide images of his or her index finger, middle finger, and ring finger of both hands
+in a conventional office environment (rather than a darkroom). The collection for each of the 6 fingers is repeated 10 times to obtain 60 finger vein images for each volunteer. Hence, MMCBNU_6000 is composed of
+6,000 images. Each image is stored in “bmp” format with a resolution of 480×640.
+1) The age of volunteers in MMCBNU_6000 varies from 16 to 72 years old.
+2) The numbers of persons with blood types A, B, AB, and O are 32, 19, 11, and 28, respectively, while 10 volunteers did not know their blood types.
+3) There are 83 males and 17 females in the 100 volunteers.
+4) The volunteers participated in MMCBNU_6000 are from 20 countries. These countries cover Asian, Europe, Africa, and America.
