This paper exploited statistical feature along with some morphological operations to detect horizontally aligned artificial textual fields in Turkish video frames, which are then extracted for content-based video indexing and retrieval system. First, projection analysis was performed to find the edges in the images and then morphological operations to convert the textual regions in images into lines. Later, false positives were eradicated by geometrical constraints and heuristics-based method. The detected candidate text regions were fed to optical character recognition (OCR) system to recognize and output the text. Finally, the recognized words were stored in database as keys for automatic content-based video indexing, which can be retrieved through provided web interface. For evaluation, a ground-truth preparation software is prepared to manually localize the text in images. Experimental results showed that our proposed method performed well on Turkish videos with overall f-measure of 95%.","PeriodicalId":312627,"journal":{"name":"2020 28th Signal Processing and Communications Applications Conference (SIU)","volume":"176 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116045642","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 satellites produce a large amount of data by traveling around the world. Efficient compression of these images are important issues. In order to solve this problem, the most used method is compression of the images with JPEG2000 method. However, distortion occurs after JPEG2000 compression, especially at low bit-rates. This situation affects the performance of some applications such as change detection, classification, anomaly detection etc. In this paper, in order to overcome compression artifacts, a very deep süper-resolution approach is proposed as post-processing after JPEG2000 decompression. In the experiments, scenes of the Onera dataset that is shared in the website of IEEE GRSS DASE are used. Experimental results show that the proposed method not only increases the image quality but also improves the change detection performance.","PeriodicalId":312627,"journal":{"name":"2020 28th Signal Processing and Communications Applications Conference (SIU)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122974552","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, despite their current success, they initially faced with overfitting issue that limits their usage. The first practical and usable solution to overfitting in deep neural networks is a simple approach known as the dropout. Dropout is a regularization approach that randomly drops connections from earlier layers during training of neural nets. Dropout is a widely used technique, especially in image classification, speech recognition and natural language processing tasks, where features created by earlier layers are mostly redundant. Usage of the dropout layer in other tasks is largely unexplored. In this study, we seek an answer to question if the dropout layer is also useful for classical regression problems. A 3 layer deep learning net with a single dropout layer with various dropout levels tested on 8 real regression datasets. According to the experiments, the dropout layer does not help over fitting.","PeriodicalId":312627,"journal":{"name":"2020 28th Signal Processing and Communications Applications Conference (SIU)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121906728","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}

Although the results of BCI studies are relatively successful, it is still an area that needs to be improved. Recent studies show that combining multiple signal recording methods (hybrid), which compensates for each other's disadvantages, will improve the performance of the BBA system. Electroencephalography + near infrared spectroscopy (EEG+NIRS) based systems have gained importance among hybrid BCI models in recent years. In this study, it was aimed to improve the system performance by working with two-class mental arithmetic based EEG+NIRS dataset which was recorded from 29 subjects. EEG oxygenated hemoglobin and deoxygenated hemoglobin signals were extracted Higuchi fractal dimension or autoregressive method based features. The extracted features were classified by k-nearest neighborhood, linear discrimination analysis (LDA), naive Bayes, decision tree, support vector machines and random forest methods. The best classification accuracy was calculated as 94.08% on average for the hybrid model with LDA. 9.31% better result was achieved with the hybrid model compared to EEG shows that the proposed method is effective for this data set.","PeriodicalId":312627,"journal":{"name":"2020 28th Signal Processing and Communications Applications Conference (SIU)","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116751451","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}

Latent Dirichlet Allocation (LDA) is the standard model for topic modeling. It shows good performance on document collections, documents being relatively long texts but it has poor performance on short texts. Topic modeling on short texts is on the rise due to the potential of social media. Thus, approaches that are able to find topics on short texts as well as long texts are sought. However, there is a lack of datasets that include both long and short texts which have the same ground-truth categories. In this work, we release a Turkish movie dataset which contain both short film descriptions and long subscripts where film genre can be considered as topic.

This paper aims to introduce an improvement of the parameter of a MPA, particularly, the gain, return loss, and bandwidth. These improvements has been investigated using Computer Simulation Technology (CST) Microwave Studio (MWS) simulator. The design is performed for 60 GHz applications. The 60 GHz band suffers from severe attenuation due to propagation. The oxygen absorption and the free-space path loss happen at 60 GHz are presumed in this study.
