Reading digital video clocks in real time is a very challenging problem. The first challenge is the clock digit localization. The existing pixel periodicity is not applicable to localizing multiple second-digit places. This article proposes a context-aware pixel periodicity method to identify the second-pixels of each clock. The second challenge is clock-digit recognition. For this task, the algorithms based a domain knowledge and deep learning technique is proposed to recognize clock digits. The proposed algorithm is better than the existing best one in two aspects. The first one is that it can read not only single digit video clock but also multiple digit video clocks. The other is that it requires a short length of a video clip. The experimental results show that the proposed algorithm can achieve 100% of accuracy in both localization and recognition for both single and multiple clocks.<\/jats:p>","DOI":"10.4018\/ijdcf.2020040102","type":"journal-article","created":{"date-parts":[[2020,1,10]],"date-time":"2020-01-10T18:20:26Z","timestamp":1578680426000},"page":"21-39","source":"Crossref","is-referenced-by-count":0,"title":["Reading Both Single and Multiple Digital Video Clocks Using Context-Aware Pixel Periodicity and Deep Learning"],"prefix":"10.4018","volume":"12","author":[{"given":"Xinguo","family":"Yu","sequence":"first","affiliation":[{"name":"Central China Normal University, Wuhan, China"}]},{"given":"Wu","family":"Song","sequence":"additional","affiliation":[{"name":"Central China Normal University, Wuhan, China"}]},{"given":"Xiaopan","family":"Lyu","sequence":"additional","affiliation":[{"name":"Central China Normal University, Wuhan, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2088-8193","authenticated-orcid":true,"given":"Bin","family":"He","sequence":"additional","affiliation":[{"name":"Central China Normal University, Wuhan, China"}]},{"given":"Nan","family":"Ye","sequence":"additional","affiliation":[{"name":"University of Queensland, Brisbane, Australia"}]}],"member":"2432","reference":[{"key":"IJDCF.2020040102-0","doi-asserted-by":"publisher","DOI":"10.1007\/s10044-011-0237-7"},{"key":"IJDCF.2020040102-1","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-540-89796-5_32"},{"key":"IJDCF.2020040102-2","first-page":"173","author":"N.Covavisaruch","year":"2004","journal-title":"Time Stamp Detection and Recognition in Video Frames"},{"key":"IJDCF.2020040102-3","doi-asserted-by":"publisher","DOI":"10.1109\/CVPR.2010.5540041"},{"key":"IJDCF.2020040102-4","doi-asserted-by":"publisher","DOI":"10.1142\/S0218001415550125"},{"key":"IJDCF.2020040102-5","article-title":"A robust approach for scene text localization using rule-based confidence map and grouping.","author":"S.Ghanei","year":"2016","journal-title":"International Journal of Pattern Recognition and Artificial Intelligence"},{"key":"IJDCF.2020040102-6","doi-asserted-by":"publisher","DOI":"10.1007\/s11263-015-0823-z"},{"key":"IJDCF.2020040102-7","doi-asserted-by":"publisher","DOI":"10.1109\/ICDAR.2011.93"},{"key":"IJDCF.2020040102-8","first-page":"II","volume":"Vol. 2","author":"Y.Li","year":"2006","journal-title":"Video clock time recognition based on temporal periodic pattern change of the digit characters.
