Inter and Intra class correlation analysis (IIcCA) for human action recognition in realistic scenarios.

In this paper we propose a new method, Inter and Intra class correlation analysis (IICCA), to handle inter and intra class variations observed in realistic scenarios. Our contribution includes learning a class specific visual representation that efficiently represents a particular action class and has a high discriminative power with respect to other action classes. We use statistical measures to extract visual words that are highly intra correlated and less inter correlated. We evaluated and compared our approach with state-of-the-art work using a realistic benchmark human action recognition dataset.6eng© 2017 IEEE.Human action recognitionInter and intra class variationCorrelation analysisUCF Sportsconference paperInformáticahttps://doi.org/10.1049/cp.2017.0149open access8th International Conference of Pattern Recognition Systems (ICPRS 2017)CC/0000027462
