Checking the correctness of perception algorithms such as those based on deep convolutional neural networks (CNN) is a formidable challenge problem. In this paper, we suggest the use of Timed Quality Temporal Logic (TQTL) as a formal language to express desirable spatio-temporal properties of a perception algorithm processing a video. While perception algorithms are traditionally tested by comparing their performance to ground truth labels, we show how TQTL can be a useful tool to determine quality of perception, and offers an alternative metric that can give useful information, even in the absence of ground truth labels. We demonstrate TQTL monitoring on two popular CNNs: YOLO and SqueezeDet, and give a comparative study of the results obtained for each architecture.", keywords = "Autonomous vehicles, Image processing, Monitoring, Perception, Quality Metrics, Temporal Logic", author = "Anand Balakrishnan and Puranic, {Aniruddh G.} and Xin Qin and Adel Dokhanchi and Deshmukh, {Jyotirmoy V.} and {Ben Amor}, Hani and Georgios Fainekos", year = "2019", month = "5", day = "14", doi = "10.23919/DATE.2019.8715114", language = "English (US)", series = "Proceedings of the 2019 Design, Automation and Test in Europe Conference and Exhibition, DATE 2019", publisher = "Institute of Electrical and Electronics Engineers Inc.", pages = "1433--1438", booktitle = "Proceedings of the 2019 Design, Automation and Test in Europe Conference and Exhibition, DATE 2019", }
