Therefore, it is required for the researchers to design systems that detect drowsiness from camera and alert the driver. There are different deep learning architectures that learn the hidden relations between patterns according to their approaches for processing input data. In this paper, the performances of adopting spatial + temporal and spatio-temporal architectures are investigated through detecting driver drowsiness. For spatial + temporal approach, 2 dimensional ResNet-34 is used along with bidirectional LSTM while spatio-temporal architecture consists of 3 dimensional ResNet-34 inflated from 2 dimensional version followed by fully connected layers. The experiments are performed on NTHU Driver Drowsiness Detection dataset and performance of capturing temporal relations is analyzed for both cases. Experiments show that spatial + temporal approach is superior than spatio-temporal approach in terms of both accuracy and speed.","PeriodicalId":115446,"journal":{"name":"2022 30th Signal Processing and Communications Applications Conference (SIU)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124944889","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}

These features can be used in algorithm improvements by measuring with UV sensors placed on the ground projection of the missile flight route in live missile tests where missiles are fired to a hot target. However, live missile tests are difficult and costly processes. In addition, it is not possible to take measurements with UV sensors from every angle and range required in these tests. For these reasons, it is important to convert the UV signatures obtained as a result of firing the stationary missile engine in a suitable environment into missile signatures approaching towards the UV sensors. Within the scope of this study, the regression studies aimed to convert the UV signatures (static missile signature) taken from the fixed engine burning tests of various missiles into the UV signatures (dynamic missile signature) of the missiles approaching towards the UV sensors are summarized.","PeriodicalId":115446,"journal":{"name":"2022 30th Signal Processing and Communications Applications Conference (SIU)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125201108","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}

In this paper, a joint focus stacking and high dynamic range (HDR) imaging method is proposed to extend the limited depth of field and dynamic range of a typical camera. The proposed method acquires a set of input images from a camera array with varying exposure and depth of field, and performs focus stacking under exposure diversity. Experimental results show significant improvement in the dynamic range and depth of field of the final focus-stacked HDR image. Additionally, the proposed method effectively handles the ghosting artifacts during the fusion process.","PeriodicalId":115446,"journal":{"name":"2022 30th Signal Processing and Communications Applications Conference (SIU)","volume":"174 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132357799","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 most important of these problems are the high path loss and the direct line of sight (LOS) requirement in most of the communication schemes. Reconfigurable intelligent surface (RIS) designs, which can be brought as a solution to the line of sight requirement have been proposed in this research. The unit cells forming these surfaces cannot be designed using metal materials due to the characteristics of electromagnetic waves with THz frequency. Graphene material, according to its controllable surface impedance properties, provides both sufficient reflection conditions and can be used to create units with different reflective phase values with varying impedance values to create the RIS structure. In this study, a certain reflection phase range was obtained on a designed RIS unit cell and RIS structures that can direct the incoming plane wave to various angles using this unit were designed and simulated in CST Microwave Studio 2019 program.","PeriodicalId":115446,"journal":{"name":"2022 30th Signal Processing and Communications Applications Conference (SIU)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133707592","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}
