The proposed method consists of license plate detection and identification of characters and numbers. In the license plate detection, the vertical edges, the vertical projection, and some operations of morphology are used to searching for license plate location. Once plate location is known, the identification of characters and numbers starts from inversion of binary image, character and number segmentation, normalization, computation of the horizontal and vertical DCT coefficients. Finally, the impulse response of FIR system of character and number are determined using the horizontal and vertical DCT coefficients as input and output of FIR system. The unknown characters or numbers on the plate number can be identified by comparison of their impulse response with the impulse responses of known characters and numbers in database, if the sum square error of them is smallest. On experiments, it found that the correct detection of license plate is about 95.52% and the accuracy of characters and numeral identification is about 81.25%.","PeriodicalId":267403,"journal":{"name":"2017 9th International Conference on Information Technology and Electrical Engineering (ICITEE)","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128662364","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 enhancement of solar cell research is widespread, but energy monitoring is time consuming. In order to reduce the workload and increase the ability of researchers, solar cell system measuring based on the microcontroller application and applying 2.4 GHz wireless module to transmit and receive data to a computer is considerated. Implementing Graphic User Interface (GUI) using Delphi program for recording the data in database and display them on the graphs. As the results, we measure DC voltage, DC current and AC voltage by comparing our instrument with digital multimeter. We observe that there are some errors in term of percentage such as 0.25 percent of DC voltage, 0.34 percent of DC current and 1.8 percent of AC voltage respectively. Our instrument can also send all voltages via wireless communication at transmission range of about 7 meters. The average of light intensity which provides the maximum voltage (20V) of solar energy is in between 15000 to 45000 lux during the day. This application may apply to the other applications in the solar energy systems.","PeriodicalId":267403,"journal":{"name":"2017 9th International Conference on Information Technology and Electrical Engineering (ICITEE)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127648193","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}

Understanding facial expressions and their meanings are crucial not only in our daily life communication, but also in many applications. For example, in marketing, the customers' facial expressions indicate their response towards a product. In artificial intelligence (AI), robots can use human facial expressions as a cue for understanding their emotion in order to respond appropriately. This paper proposes a method for recognizing human facial expressions from images using local Gabor filter, Principal Component Analysis (PCA) and Linear Discriminant Analysis (LDA). The system starts by applying the face detection algorithm to detect the face from an image. From the face, the system extracts the Gabor filter responses and maps these responses into the novel feature subspace using the joined framework of PCA and LDA. Note that, in our framework, the principle component removal is also integrated into the framework. Based on the weighted neighbor approach, the system finally classifies human expressions into 4 different classes: anger, surprise, happiness and neutral. The results demonstrate that our approach significantly outperforms the baselines.","PeriodicalId":267403,"journal":{"name":"2017 9th International Conference on Information Technology and Electrical Engineering (ICITEE)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133015997","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 inter-networking of all of these devices known as “the internet of things (IoT)” is expected to have tens of billions of devices, mostly wireless, definitely incurring a coexistence or interference problem. The ubiquitous industrial, scientific and medical (ISM) radio band at 2.4GHz, in particular, one of the candidate band for IoT is heavily oversubscribed due to its unlicensed nature and could become all but unusable for priority systems in a densely populated area in the future at the present rate of growth of 2.4GHz transmitters and networks. In our study, the communications of the “last 100 meters” of an IoT network, i.e., from devices to an access point (AP) are considered. The interference suppression algorithms using the probability of false alarm PFA based methods, i.e., the Neyman-Pearson (NP) criterion and the localization algorithm based on double-thresholding (LAD) are applied to enhance the transmission bit error rate (BER) performances in various scenarios. Besides the traditional fixed threshold approach, an adaptive threshold approaches are proposed to enhance the performances in frequency selective fading channels. The simulation results show that the proposed methods excellently work even in an IoT network, which contains a large number of devices.","PeriodicalId":267403,"journal":{"name":"2017 9th International Conference on Information Technology and Electrical Engineering (ICITEE)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133453372","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}
