Fingerprint identification system is mainly consisted of fingerprint achieving, fingerprint classification and fingerprint matching. Fingerprint matching is the key to the system and effects on the precision and efficiency of the whole system directly. Fingerprints are matched mainly based on their fingerprint texture pattern which can be described with the orientation field of fingerprints. A ...

Fingerprint identification is divided into fingerprint pretreatment, fingerprint feature extract ion and a fingerprint match. Based on embedded technology and fingerprints processing algorithms, embedded automatic fingerprint identification system fingerprint identification of various processes study the algorithm, this paper expounds the characteristics of various algorithm with using details.

Objective: Boswellic acids (BAs) are active constituents of plant Boswellia serrata. In the present study boswellic acids were extracted from Boswellia serrata and dry methanolic extracts were quantified by HPLC and HPTLC. Method: A gradient HPLC method was used for the quantification of the boswellic acids; 11-keto-β-boswellic acid (KBA) and 3acetyl-11-keto-β-boswellic acid (AKBA). A direct HP...

Hundred Fusarium culmorum strains, isolated from freshly harvested maize grain samples from Southern parts of India, were incubated in czapek-dox medium and analyzed for trichothecene (DON/NIV) production. The mPCR assay was standardized targeting trichothecene metabolic pathway genes viz., Tri6, Tri7, Tri13 for detection of trichothecene (DON/NIV) chemotypes and rDNA gene for specific detectio...

To estimate phenols and flavonoids, enzymic antioxidants in the leaves of Boerhaavia erecta (LBE). The sample was extracted with 0.1M phosphate buffer for the analysis of phenols, flavonoids and antioxidants. The total phenolic content and total flavonoids in LBE were measured using Folin-Ciocalteau and aluminium chloride colorimetric methods respectively. The activity of Superoxide Dismutase (...

Fingerprint ridge frequency is a global feature, which is most prominently different in fingerprints of men and woman, and it also changes within the maturing period of a person. This paper proposes the method of fingerprint pre-classification, based on the ridge frequency replacement by the density of edge points of the ridge boundary. This method is to be used after applying the common steps ...

BACKGROUND Nowadays, plants have been considered as powerful agents for treatment of disorders due to their traditional use. Plants have a special role in the treatment of various diseases in Ayurveda. Liver disorders with their devastating outcomes have been discussed in Ayurveda as well. OBJECTIVES In the present study, polyherbal products (L52 and L38) were retrieved from Ayurveda and its ...

Mucuna pruriens Linn. is an important medicinal plant used for treatment of Parkinson's disease and many others in ancient Indian medical system. L-DOPA extracted from seeds of Mucuna is a constituent of more than 200 indigenous drug formulations and is more effective as drug than the synthetic counterpart. A densitometric high performance thin-layer chromatographic (HPTLC) method was developed...

Alpinetin is a flavonoidal constituent of seeds of Amomum subulatum Roxb., recently reported to possess vasorelaxant and antiHIV activities. Simple, accurate and precise HPLC and HPTLC methods were developed for the analysis of alpinetin in A. subulatum seed extracts and extraction technique was optimized to get maximum yield using conventional, ultrasonic and matrix solid phase dispersion extr...
