In this paper, we propose a new feature extraction algorithm based on Independent Component Analysis (ICA) for iris recognition. A conventional method based on Gabor wavelets should select the parameters (e.g., spatial location, orientation, and frequency) for fixed bases. We apply ICA to generating optimal basis vectors for the problem of extracting(More)
Cryptographic systems have been widely used in many information security applications. One main challenge that these systems have faced has been how to protect private keys from attackers. Recently, biometric cryptosystems have been introduced as a reliable way of concealing private keys by using biometric data. A fuzzy vault refers to a biometric(More)
This paper proposes a free parking space detection system by using motion stereo-based 3D reconstruction. An image sequence is acquired with a single rearview fisheye camera and the view behind the automobile is three-dimensionally reconstructed by using point correspondences. Metric information is recovered from the camera height ratio and free parking(More)
Recently, crypto-biometric systems have been studied for solving the key management problem of cryptographic systems and protecting templates in biometric systems at the same time. The fuzzy vault system is a well-known crypto-biometric system. We propose a new method of applying iris data to the fuzzy vault. Our research has following two advantages and(More)
An automatic parking system provides convenience for drivers by automatically finding free parking spaces and steering automobiles toward them. This paper proposes a vision-based free parking space detection system. The proposed method consists of two stages. First, the automobile rearview is three-dimensionally reconstructed using the optical flow-based(More)
This paper proposes an algorithm for rejecting false matches (known as outliers) in image pairs acquired with automobile-mounted cameras. Many intelligent vehicle applications require point correspondences for motion estimation and 3D reconstruction which can be affected by outliers. We use the property of automobile motion to reject outliers. Automobile(More)
We propose an invariant key generation method using an iris image. In conventional iris recognition systems, iris features are not consistent because most feature extraction techniques are sensitive to variations of the captured iris image data. We introduce an invariant binary feature which is defined as the iris key. Regardless of iris image variations,(More)

Locking folders effectively protects data from malicious programs, such as Viruses, Worms, and Trojans. Biometric template protection is a hot topic of research recently. Fuzzy vault is a recently developed construct which binds secret key (Password) and biometric information to provide template protection. In this paper we propose a biometric folder(More)
