Instance segmentation is one of the most important tasks used in many areas including autonomous vehicles and video surveillance because such areas require both high frames per second (FPS) and high accuracy. In this paper, we propose a method of attaching path aggregation network and attention gate based on real-time instance segmentation model, YOLACT, to increase the accuracy of instance segmentation. As a result of applying the proposed method to the YOLACT framework, the processing speed drops slightly by 2.7%, but the accuracy increases significantly up to 1.4AP, while still maintaining realtime processing of 32.6FPS.","PeriodicalId":270577,"journal":{"name":"2020 International SoC Design Conference (ISOCC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113979098","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}

It compares the phases of two input clock signals and then produce a binary lead/lag signal to indicate which clock signal arrives earlier. The resolution of a PD often determines the accuracy of a DLL in terms of the phase error. Unfortunately, a traditional cell-based PD is strongly susceptible to the process variation. In this paper, we propose a “Voting PD design” to alleviate this problem. First, a number of primitive phase detectors are incorporated, and then their primitive results undergo a majority voting process to produce the final lead/lag signal, and thereby enhancing the overall resolution. A statistical approximation shows that process variation can be compressed to 53% using a voting group of 5 primitive phase detectors.","PeriodicalId":270577,"journal":{"name":"2020 International SoC Design Conference (ISOCC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128974923","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}
