In this paper, a novel online fingerprint verification algorithm and distribution system is proposed. In the beginning, fingerprint acquisition, image preprocessing, and feature extraction are conducted on workstations. Then, the extracted feature is transmitted over the internet. Finally, fingerprint verification is processed on a server through web-based database query. For the fingerprint fe...

In many cases the average fingerprint ridge frequency in the whole fingerprint image should be determined. This parameter is, among other things, very important in procedures, where so-called fingerprint reference point has to be located. Unfortunately, as far, ridges frequency has been determined a priori, on the basis of anthropological measurements of the human population. This parameter is ...

The deployment of a fingerprint positioning method consists of an offline phase and a real-time phase. During the offline phase, a fingerprint database is built. This process is tedious and time consuming. Even so, the majority of WiFi-based indoor positioning methods implemented in practical indoor location–based service (ILBS) systems are the fingerprint method, because this method is accurat...

Fingerprint authentication is the most consistent and practicable methods of person appreciation. The only problem with functionality of Fingerprint authentication System is it depends on the eminence of image. The quality of fingerprint image affects by both surroundings and scanner’s-surface. The Fingerprint Trivia-Matching is not possible until the eminence of fingerprint image improve. The ...

The chemical analysis and quality control of Ginkgo leaves and extracts is reviewed. Important constituents present in the medicinally used leaves are the terpene trilactones, i.e., ginkgolides A, B, C, J and bilobalide, many flavonol glycosides, biflavones, proanthocyanidins, alkylphenols, simple phenolic acids, 6-hydroxykynurenic acid, 4-O-methylpyridoxine and polyprenols. In the commercially...

BACKGROUND The employment of well characterized test samples prepared from authenticated, high quality medicinal plant materials is key to reproducible herbal research. The present study aims to demonstrate a quality assurance program covering the acquisition, botanical validation, chemical standardization and good manufacturing practices (GMP) production of IBS-20, a 20-herb Chinese herbal for...

Fingerprint identification is one of the oldest and popularly used forms of biometric identification system. Fingerprint image quality is of much importance to achieve high performance in Automatic Fingerprint Identification System (AFIS). Most of the fingerprint Recognition system relies on fingerprint ridges to extract the features. The fingerprint images which are corrupted due to variations...

Touch-less based fingerprint verification systems are free from the problems of image deformation, latent fingerprint issues and so forth that appear in the contemporary touch based fingerprint verification systems. Coupled with template protection mechanism, a touch-less fingerprint verification system is further enhanced. In this paper, a secure end-to-end touch-less fingerprint verification ...

Background and objectives: Hibiscus sabdariffa L. (roselle) sepals, commonly known as bissap is prepared as a cold drink which is widely drunk in Ghana and across West-Africa for their medicinal and nutritional properties. The plant is known to have anti-hypertensive, anti-hyperlipidemic, anticancer, anti-diabetic and anti-inflammatory activities. For such a widely sol...
