Unlike frame-based cameras, the data format of DVS makes it difficult for traditional algorithms to process it directly. On the other hand, as a new type of brain-like neural network, the spiking neural network is specially used to process spiking data, and it is well suited for this type of event-based camera. In addition, because of the rapid development of neuromorphic hardware in recent years, it is possible to deploy SNN applications on edge-side system-on-chip. Therefore, based on the characteristics of dynamic vision sensors, this paper designs a spike encoding module and an SNN for processing sensor information. We use selective search to accomplish object tracking by classifying targets and backgrounds. The SNN can achieve 98.66% classification accuracy on our synthetic test dataset, and the tracking algorithm can achieve over 1000 fps after quantizing and compiling the network to the hardware simulator.","PeriodicalId":325602,"journal":{"name":"2022 IEEE International Conference on Integrated Circuits, Technologies and Applications (ICTA)","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114576086","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}
