In the steady-state, depending on the test object, the signal may contain only fundamental frequency and harmonics. Then, in case of poor mechanical condition, diagnostic signal contains also some foreign frequencies. Using signal of finite length for computing its spectrum causes some deviations in spectrum structure. It can be the reason for misinterpretation because of array frequencies occurring in DFT, which in fact do not exist in the signal and existing frequencies, which have incorrect amplitude. To reduce this effect, the window function can be used. Taking into consideration the special spectral structure of diagnostic signals in the steady-state, it is possible to adjust parameters of signals in such a way to eliminate any distortion for regular frequencies. For this purpose, if further analysis requires a fixed number of signal samples, by signal resampling, spectral resolution can be adjusted to the harmonics existing in the signal, especially, when processed are signals already recorded with unwanted sampling frequencies.","PeriodicalId":302860,"journal":{"name":"2017 International Conference on Systems, Signals and Image Processing (IWSSIP)","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121166900","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}

More improved face detectors that can handle uncontrolled face detection scenarios have achieved by applying more advanced features such as Histogram of oriented Gradients (HoG). The great improvement in accuracy delivered by these methods has been accompanied by a large increase in the computational burden, which limited adoption in embedded solutions particularly. The improved bitmap-based HoG approaches resolved this problem by limitation of HoG window to non-rectangular irregular pattern of the object and its boundary avoid processing of extra background and (partially) foreground pixels respectively. In this paper, bHoG and bbHoG along with three different bitmap patterns are applied to the face detection problem to not only benefits from the robustness of HoG, but also to amend its high computational cost significantly. Experimental results show an decrease of 92.5% in the workload associated with HoG/SVM classifiers compared to the state-of-the-art, along with approximately the same performance as standard HoG and an average decrease about 5% in recall and precision in comparison for the smaller cell sizes.","PeriodicalId":302860,"journal":{"name":"2017 International Conference on Systems, Signals and Image Processing (IWSSIP)","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121878598","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}

Urban Traffic Information System (UTIS) was developed as a mobile detector for measuring link travel speeds in South Korea. UTIS is mainly a means of collecting enhanced roadway condition information and then broadcasting related traveler information and various alerts back to vehicles. The proposed wireless media is based on UTIS technology operating at 5.725∼5.825 GHz in South Korea. Under the UTIS concept, vehicles will be equipped with an UTIS radio, a highly accurate on-board positioning system, an appropriately configured on-board computer to facilitate communications, support various applications, and provide an interface for the driver. This equipment is collectively referred to as the On-Board Equipment (OBE). Vehicles communicate with Roadside Equipment (RSE), which is linked to the specialized UTIS network. RSEs and CCTVs are positioned at major signaled intersections and along major arterial roads. This study describes a model developed for estimating reliable and accurate average roadway link travel speeds using UTIS and CCTV. The algorithm estimates link travel times using a robust data-fusion procedure to provide accurate link travel speeds and traffic information to the public.","PeriodicalId":302860,"journal":{"name":"2017 International Conference on Systems, Signals and Image Processing (IWSSIP)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127767190","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}
