Popular choices for multiple object detection in video sequences include convolutional neural networks, such as YOLO, MobileNet-SSD and Faster R-CNN, which typically split image frames to small rectangular regions and attempts to find bounding boxes of sought–after objects. Current research of such methods mostly focus on speeding–up the implementations or improving the network layers’ learning properties. As a new approach, this work appends a simple post processing stage at the end of such networks to reinforce decision robustness using a sequential decision process through sequential video frames. The sequential frames provide a better confidence on the existence of an object, when a probable object was also estimated in the previous frame. Once the confidence level overshoots a predetermined threshold, objects that are difficult to be detected in a single frame get accurately detected.","PeriodicalId":115446,"journal":{"name":"2022 30th Signal Processing and Communications Applications Conference (SIU)","volume":"2021 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":"117176639","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}

Most of the game companies and developers use procedural methods to automate the design process. The visual content produced by these algorithms is limited in terms of variation. In this paper, we propose to use Generative Adversarial Networks (GANs) for visual content production. Two different rpg and dnd visual image datasets were collected over the internet for training and 6 different GAN models were trained on them. In 3 of 18 experiments, transfer learning methods are used because of the limited datasets. The Frechet Inception Distance metric was used to compare the model results. As a result, SNGAN was the most successful in both datasets. Moreover, the transfer learning method (WGAN-GP, BigGAN) was more successful than the from scratch method.","PeriodicalId":115446,"journal":{"name":"2022 30th Signal Processing and Communications Applications Conference (SIU)","volume":"30 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":"128236864","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}

Particularly, a continuous decrease in the number of voters between 2006 and 2018, is achieved. This study investigates whether acquiring political information from social networks (e.g. friends and relatives) and mass media (e.g. tv and radio) is related to the decision of people to vote or not. Linear regression analysis is applied to discover the relationship between turnout rate and political means. It is found that getting informed about politics from relatives, acquaintances, political organizations, trade unions, radio and weekly magazines are not statistically meaningful to explain changes in turnout rates. Friends have an impact on turnout rates in a negative direction. Besides, getting information from tv and newspapers has a positive impact on turnout rates. It is also observed that mass media is more effective than social networks on turnout rates.","PeriodicalId":115446,"journal":{"name":"2022 30th Signal Processing and Communications Applications Conference (SIU)","volume":"16 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":"129929727","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}

Various queue analysis and management tools have been developed to reduce this wasted time. One of these tools is the systems that analyze the queues and calculate the average waiting time. In this study, a computer vision method that calculates the average waiting time by detecting and tracking the people waiting in the queue is proposed. Thanks to this method, it is aimed that people can see how long they will wait before queuing. In the developed method, people waiting in a direction were analyzed by using object detection methods, and the times of joining and leaving the queue were tried to be determined. Due to the high processing load of the object detection algorithms, object tracking algorithms are used so that the method can work in real-time.

Visual field testing is required for monitoring and diagnosis of several disorders, including glaucoma, which affects more than 80 million individuals. While the patient is fixated at a certain place, light of various luminosities is sent to fixed locations, and the sensitivities to light at each position are calculated by recording the patient’s responses to observed stimuli. Virtual reality headsets have just begun to be used to conduct visual field assessments due to their design and digital displays. However, because the testing takes so long, patients become fatigued, which reduces cooperation and test accuracy. It also restricts the number of tests a clinic may do in a single day. The number of testable point locations is expanded using a digital screen in this article, and the effect of selecting an optimal subset of sites, which is discovered using a reinforcement learning approach to reduce test length, is studied. In addition, the impact of employing predicted future visual field test results in testing on the test time is compared to traditional testing procedures.","PeriodicalId":115446,"journal":{"name":"2022 30th Signal Processing and Communications Applications Conference (SIU)","volume":"166 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":"116308997","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}
