3D Ultrasound palm vein pattern for biometric recognition

Abstract

In this work, an ultrasound technique for achieving 3D palm vein patterns for biometric recognition purposes is proposed and experimentally tested. Commercial ultrasound\ud imaging machine and linear arrays have been employed. Both imaging and power Doppler analysis have been performed to detect veins. The probe is moved in the directional orthogonal to the array by an automated scanning system and at each step a 2D frame is captured and stored to form a 3D matrix.\ud The data from the 3D matrix are elaborated for achieving 3D ultrasonic vein patterns. The proposed technique has been applied to acquire hand vein patterns of about a dozen of distinct volunteers, which are opportunely rendered and discussed

Experimental Validation of a Reliable Palmprint Recognition System Based on 2D Ultrasound Images

“…Additionally, more recent feature extraction techniques based on deep learning [50] or collaborative representation [51] are under investigation. Finally, the possibility of extracting other biometrics like vein pattern [22,23] and inner hand geometry [19] from the same acquired volume, implementing in this way a multimodal system, will be explored.…”

“…Several sensor technologies applications, including single piezoelectric elements, piezocomposite arrays, and more recently capacitive Micromachined Ultrasonic Transducers (cMUTs) and piezoelectric Micromachined Ultrasonic Transducers (pMUTs), as well as various techniques like pulse-echo, impediography, Doppler analysis, photoacoustics, and acoustic holography [18] have been tested to generate ultrasonic images for biometric recognition. Not only fingerprint, but also hand or finger geometry [19,20], vein pattern [21][22][23], and palmprint have been investigated.…”

Ultrasound Systems for Biometric Recognition

“…Results have shown that two kinds of 3D information can be extracted: the 3D profile of the palm, which can be achieved with optical methods based on structured-light imaging as well [87], and palm lines’ depth, which instead can be achieved only with the ultrasound. The same set up was also used to extract, through power Doppler analysis, 3D palm vein patterns [88], which provide improved distinctiveness with respect to 2D vein patterns achievable with classical techniques (see Figure 5).…”

Review on a palm vein infrared image acquisition system

“…Special help is needed in visualizing the vein pattern effectively, as shared in several literatures regarding the potential light spectrum that can be used for the purpose [2] [8] [11]. Other alternatives in visualizing the vein pattern are motivated by the practice done in the medical field such as the use of X-ray and also ultrasound [11] [12]. Of all the options, the infrared (IR) light seems a promising prospect with regard to the biometric purpose.…”
