In particular, our system uses a Raspberry-Pi camera to collect realtime video and detect face masks by implementing a classification model on Raspberry Pi 3 in public places. The face mask detector is built based on MobileNetV2, with ImageNet pre-trained weights, to detect three cases of correctly wearing, incorrectly wearing and not wearing a mask. We also design a human temperature measurement framework by deploying a temperature sensor on the Raspberry Pi 3. The numerical results prove the practicality and effectiveness of our embedded systems compared to some state-of-the-art researches. The results of accuracy rate in detecting three cases of wearing a face mask are 98.61% based on the training results and 97.63% for validation results. Meanwhile, our proposed system needs a short time of 6 seconds for each person to be tested through the whole process of face mask detection and human forehead temperature measurement.","PeriodicalId":296963,"journal":{"name":"2021 8th NAFOSTED Conference on Information and Computer Science (NICS)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127193006","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 majority of existing trackers typically compute target template and search image features independently, then utilize cross-correlation to predict the possibility of an object appearing at each spatial position in the search image for target localization. This paper proposes a Siamese network for feature enhancement and aggregation between the target template and the search image by utilizing a lightweight transformer with several linear self- and cross-attention layers. With anchor-free head prediction, the suggested framework is simple and effective. Extensive experiments on visual tracking benchmarks such as VOT2018, UAV123, and OTB100 demonstrates that our tracker achieves state-of-the-art performance and operates at a real-time frame rate of 39 fps.","PeriodicalId":296963,"journal":{"name":"2021 8th NAFOSTED Conference on Information and Computer Science (NICS)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122376839","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, due to the rapid spread of various new attacks, developing a robust IDS that can effectively detect novel attacks and prevent them from devastating network systems is a challenging task. Recently, deep neural networks (DNNs) have been widely used to enhance the accuracy of IDSs in detecting network intrusions. Nevertheless, the performance of DNN highly depends on the representation of the input data. In this paper, we introduce a novel method called DeepInsight-Convolutional Neural Network-Intrusion Detection System (DC-IDS). In CD-IDS, the DeepInsight technique is used to transform the network traffic data into a new representation in the form of an image. This new representation of the traffic data is then used as the input of a Convolutional Neural Network (CNN). We evaluate our proposed technique using an extensive experiment on five IDS datasets. The experimental results show that the proposed model enhances the performance of IDSs in detecting various network attacks compared to different popular machine learning algorithms.","PeriodicalId":296963,"journal":{"name":"2021 8th NAFOSTED Conference on Information and Computer Science (NICS)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126669144","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 basic principle of change detection is to analyse the difference images generated from two Synthetic Aperture Radar images captured in the same geographic area at two different times. The popular operators used to create difference images are traditional subtraction, ratio, logarithm based ones and modified versions of them, which can use pixel information in the local or global areas. A challenge in detecting changes is to reduce impacts of speckle noises inherently existing in Synthetic Aperture Radar images on the accuracy of the detection. This paper proposed a novel algorithm to create the difference images based on averaging heterogeneous factors of corresponding neighbourhood areas in the two images. The resultant difference image is then filtered by the average filter to reject remaining speckle noises.","PeriodicalId":296963,"journal":{"name":"2021 8th NAFOSTED Conference on Information and Computer Science (NICS)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126787939","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}
