CASIA虹膜图像数据版本1.0(BIT——CASIA Iris Image Database Version 1.0 )

数据介绍:

CASIA Iris Image Database for Testing Version 1.0 (or IR-TestV1) contains 10,000 iris images of 2,000 eyes from 1,000 subjects. The iris images of IR-TestV1 were captured using IrisGuard AD100 camera in one session.

BIT——CASIA Iris Image Database Version 1.0

Description

Iris recognition has been an active research topic in recent years because of its high accuracy. There is not any public iris database while there are many face and fingerprint databases. Lacking of iris data may be a block to the research of iris recognition. To promote the research, National Laboratory of Pattern Recognition (NLPR), Institute of Automation (IA), Chinese Academy of Sciences (CAS) will provide iris database freely for iris recognition researchers.

Iris images of CASIA V1.0 (CASIA-IrisV1) were captured with a homemade iris camera. Eight 850nm NIR illuminators are circularly arranged around the sensor to make sure that iris is uniformly and adequately illuminated. In order to protect our IPR in the design of iris camera (especially the NIR illumination scheme) before appropriate patents were granted, the pupil regions of all iris images in CASIA-IrisV1 were automatically detected and replaced with a circular region of constant intensity to mask out the specular reflections from the NIR illuminators before public release. Clearly, such processing may affect pupil detection but has no effects on other components of an iris recognition system such as iris feature extraction since iris feature extraction only uses the image data in the region between the pupil and the sclera, i.e. the ring-shaped iris region.

●Data Information

The file name of each image in CASIA-IrisV1 is unique to each other and denotes some useful properties associated with the image such as session ID, class ID, image ID etc.

The images of CASIA-IrisV1 are stored as:

$root path$/XXX/S/XXX_S_Y.bmp

XXX: the unique identifier of eye, range from 001 to 108.

S: the index of session, denotes the first session and the second session.

Y: the index of image in the same session. Range from 1 to 3 in the first session, 1 to 4 in the second session.

Therefore XXX_S_Y:bmp means the iris image with index Y in session S from eye XXX.
