Performance Analysis for Recognition of Image With Alphanumeric Characters Under Different Environmental Conditions

Paramvir Singh,Rashpinder Kaur,Gurjinder Singh 보안공학연구지원센터 2015 International Journal of Hybrid Information Techno Vol.8 No.7
In this recent era of technological development, innovation advances in every aspect of life can be easily seen. Automatic systems were developing at very fast pace. Automatic license late recognition is one of the systems that help in developing intelligent transport system in a city or country. This also finds application in the areas of vehicle surveillance, border security, toll tax management etc. This paper evaluates the performance analysis for recognition of image with alphanumeric characters under different environmental conditions. The overall performance recognition rate was 97.57%

A Comparative Analysis of Adaptive IIR Filtering Techniques using LabVIEW

Divya Sharma,Rashpinder Kaur,Gurjinder Singh 보안공학연구지원센터 2015 International Journal of Hybrid Information Techno Vol.8 No.8
Removal of noises from real-time speech signal is a typical problem. The signal interference initiated by background noise is a major problem in voice communication systems. Adaptive Filtering methods have emerged as an important technology for communication systems. This technique has been employed to improve the quality of the speech signal by cancelling the undesirable phenomenon such as acoustic noise. In this paper, for the removal of additional noise from speech signal an adaptive filter has been designed using LMS, NLMS, SLMS and VSS-LMS algorithms. This paper presents the instigation of Least Mean Square algorithm (LMS), Normalized Least Mean Square algorithm (NLMS), Sign Least mean square algorithm (SLMS) and Variable step size (VSS) algorithm on an infinite impulse response (IIR) filter using adaptive filter toolkit of LabVIEW software. User interface is designed using LabVIEW to obtain the learning curves for these adaptive algorithms. The final results show the comparison of the performance of the entire proposed algorithms with each other. The complete performance of the designed system in terms of stability and convergence rate has been observed.

Abstract An innovative and facile sensing approach for common inorganic anions present in aqueous media has been developed using nanocomposites of europium doped graphene quantum dots (GQDs:Eu) with zeolitic imidazole frameworks (ZIF-8). GQDs:Eu, prepared initially by solvothermal approach (at <10nm in diameter), exhibited a strong and intense blue emission at 430nm when dispersed in ethanol. ZIF-8 nanocubes, synthesized on a parallel basis, were in a fairly uniform size distribution (e.g., 185nm in diameter). The formation of nanocomposites by surface adsorption (between GQDs:Eu and ZIF-8) led to significant increase in fluorescence intensity as observed through photo-luminescence spectroscopy. Their interactions with anions (e.g., in terms of variations in the fluorescence intensity) were initially checked against sulfide and other anionic species (e.g., Br−, Cl−, F−, and NO3 −). Among the tested ions, GQDs:Eu-ZIF-8 were found to effectively and sensitively detect sulfide (S2−) with significantly high turn on fluorescence. The feasibility of this nanosensing system was explored further toward the detection of S2− ions. These nanocomposites were thus demonstrated to be feasible for solution-based sensing of S2− ions with high reproducibility and sensitivity at limit of detection (LOD) of 0.12ppm.
