One of the main factors affecting the accuracy of LPR is the quality of the image containing the plate. In case of video-based solutions, many frames are captured for the same car. Super Resolution (SR) techniques can be used for enhancing LPR accuracy by constructing one high resolution image from a number of low resolution images that belong to the same car. However because of the nature of the detected object (car plate), motion analysis as well as object perspective correction need to be taken into consideration when applying the SR algorithm over the provided series of video frames containing the moving car, in order to enhance the resolution of the plate area. This paper aims at providing an implementation for a SR algorithm where input frames are put together into one high-resolution image after detecting the license plate and removing the noisy frames to provide one clear and focused image as an output. OpenCV library was modified to support this implementation. This implementation enhanced the accuracy of an LPR solution by approximately 7% enhancement while trying to not increase the computational complexity of the original solution.","PeriodicalId":170532,"journal":{"name":"2017 12th International Conference on Computer Engineering and Systems (ICCES)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125936593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The complexity of the problem increases as the diversity of the pedestrians in the scene being analyzed increases. Different approaches have been proposed. Among these approaches, the ones that involve supervised techniques for head detection have shown robust results and better accuracy. In this paper, we provide a comparison of the accuracy and performance of cascaded classifiers based on two different feature extractors, notably, the Haar-Like and the Local Binary Pattern (LBP) features extractors. It has been found that increasing the diversity and size of the training dataset leads to improvements in the resulting detectors. Therefore, four different training datasets have been constructed using standard training sets as well as our own created images for crowded scenes. Moreover, we introduce a tuning scheme for the parameters of the detector. The results obtained exceeded 80% for precision on high density images and more than 90% on lower density images.","PeriodicalId":170532,"journal":{"name":"2017 12th International Conference on Computer Engineering and Systems (ICCES)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126594021","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Resonant converters implement soft switching mechanisms like zero current switching (ZCS) and zero voltage switching (ZVS) which allows for high frequency operation together with minimum switching losses. A resonant DC-DC converter is proposed for grid connected double stage photovoltaic (PV) system. A LLC resonant converter is applied to boost the PV array terminal voltage and carry out maximum power point tracking (MPPT). The incremental conductance concept is applied using a PI controller for maximum power extraction from the PV array. A neutral point clamped three level voltage source inverter (VSI) is used to interface the PV system with the grid. The VSI controller performs two tasks; regulating the voltage of the DC bus and synchronizing injected currents with grid voltages to realize a unity power factor. A simulation study executed in MATLAB/SIMULINK environment is presented to verify the dynamic response of the proposed system to different kinds of disturbance in solar irradiance.","PeriodicalId":170532,"journal":{"name":"2017 12th International Conference on Computer Engineering and Systems (ICCES)","volume":"7 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114104501","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, with increased use of Global Navigation Satellite Systems (GNSS) comes a major challenge — GNSS signal jamming, which is an intentional form of interference. Nearly all electronic equipment using services generated by GNSS receivers is susceptible to jamming, and its effects include degradation in received signal power and receiver clock drift. Jamming signals are categorized as narrowband and wideband signals according to the bandwidth of the target signal. One common type that has recently been researched is White Gaussian Noise (WGN) jamming. Several studies investigated the impact of such signal jamming on the performance of GNSS receivers under a variety of jamming conditions. This paper, on the contrary, investigates the effects of White Gaussian Noise jamming on the performance of both high-sensitivity and standard GNSS commercial receivers. Additionally, the performance of GPS-only receivers versus combined GPS/GLONASS receivers under jamming scenarios is explored. This study used receivers by NovAtel and UBlox, with simulation scenarios created using Spirent SimGEN™ with the GSS6700 Multi-GNSS Simulator. The jamming signals were generated using an Agilent interference signal generator (ISG) unit. The results show that the receivers responded differently to the jamming signals. Dilution of Precision (DOP) and the Carrier-to-Noise (C/N0) were the main measures used for the evaluation process. The results show that multi-constellation receivers attained higher resistance for signal jamming effects than GPS only receivers.","PeriodicalId":170532,"journal":{"name":"2017 12th International Conference on Computer Engineering and Systems (ICCES)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131366756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
