Ancak, artan gürültü oranı, uzun tarama süreleri ve donanım maliyetlerinden ötürü yüksek çözünürlüklü görüntülerin edinimi pratikte mümkün olmayabilir. Bu durumlarda, düşük çözünürlüklü görüntülerden yüksek çözünürlüklü görüntülerin üretilebilmesi alternatif bir çözüm olabilir. Yaygın yöntemler tek bir görüntünün süper çözünürlüğünü yapar. Ancak, çok kontrastlı MRG’de, tek bir kontrastın düşük çözünürlüklü görüntüsü başarılı bir netleştirme için gerekli ön bilgiyi içermez. Gerekli bilgiyi zenginleştirebilmek için, farklı kontrastlardaki tamamlayıcı ön bilgiler kullanılabilir. Bu sebeple, bu çalışmada birden çok kontrasta ait görüntüleri eşzamanlı olarak netleştiren bir çoklu kontrast MRG süper çözünürlük yöntemi önerilmiştir. Önerilen yöntem yüksek frekans detaylarını daha iyi kurtararak olabildiğince gerçekçi hedef görüntüler üretebilen koşullu çekişmeli üretici ağlara dayanmaktadır. Çoklu kontrast MR görüntüleri içeren veri setinde yapılan sayısal ve görsel değerlendirmeler, önerilen yöntemin alternatif tekli görüntü MRG süper çözünürlük yönteminden daha üstün performans gösterdiğini ortaya koymuştur.","PeriodicalId":312627,"journal":{"name":"2020 28th Signal Processing and Communications Applications Conference (SIU)","volume":"12 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":"128145044","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}

A possible strong candidate for future URLLC networks is sparse vector coding (SVC), which enables a superior performance in terms of bit error rate (BER). In SVC, virtual digital domain (VDD) and compressed sensing (CS) algorithms are used to encode and decode information. In this paper, orthogonal frequency division multiplexing (OFDM)-based a novel system called orthogonal frequency division multiplexing with codebook index modulation (OFDM-CIM) and which can meet the needs of URLLC systems has been proposed. In OFDM-CIM, information bits are transmitted via both active subcarrier indices and codebook indices. As a result of computer simulations, OFDMCIM is presented as a strong candidate for next generation communication systems.","PeriodicalId":312627,"journal":{"name":"2020 28th Signal Processing and Communications Applications Conference (SIU)","volume":"56 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":"132537658","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}

This makes it difficult to diagnose heart diseases medically. In this study, the presence of heart diseases was determined by using machine learning algorithms. In this study, the data obtained from the patients were weighted according to their effects on the success rate. In this study, a method is proposed for determine weight coefficient.

Misdiagnosis of brain tumor types, both prevents the patient's response to treatment effectively and reduce the chance of survival. This study proposes a solution for the classification of brain tumors using MR images. The most common brain tumors, glioma, meningioma and pituitary, are detected using convolutional neural networks. The convolutional network is trained and tested on an accessible Figshare dataset containing 3064 MR images using four different optimizers. AUC, sensitivity, specificity and accuracy are used as performance measure. The proposed method is comparable to the literature and classifies brain tumors with an average accuracy of 96.84% and a maximum accuracy of 97.75%.","PeriodicalId":312627,"journal":{"name":"2020 28th Signal Processing and Communications Applications Conference (SIU)","volume":"18 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":"132120474","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}

We present a deep learning method for skin lesion classification by fusing and fine-tuning three pre-trained deep learning architectures (Xception, Inception-ResNet-V2, and NasNetLarge) using training images provided by ISIC2019 organizers. Additionally, the outliers and the heavy class imbalance are addressed to further enhance the classification of the lesion.

However, they are often criticized in terms of spatial consistency. As such, they have received various extensions through the last few years, in the form of dilated convolutions and skip connections and more. In this paper, we address the same issue by feeding attribute filtered images, that contain inherently a multiscale hierarchical representation of the underlying image, as input to a segmentation network, in an effort to both accelerate convergence and render easier the feature learning task of the bottom layers. We validate our approach through the production of land-use and land-cover maps for a large area of Turkey using Sentinel 2 multispectral images and ground truth from the Copernicus Land Monitoring Service.","PeriodicalId":312627,"journal":{"name":"2020 28th Signal Processing and Communications Applications Conference (SIU)","volume":"46 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":"114195087","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}
