“…Comparison with the State of the Art. We compared our model, referred to as SCC-Heatmap, to deep learningbased methods that leverage relationship modeling (CCNN-IT (Walecki et al, 2017), KBSS (Zhang et al, 2018a), BORMIR (Zhang et al, 2018b)) and the recent work KJRE (Zhang et al, 2019). Additionally, since our method is based on heatmap regression, we also directly applied two state-of-the-art regression models, Hourglass (Newell, Yang, and Deng, 2016) and ResNet-Deconv (Xiao, Wu, and Wei, 2018), for AU intensity estimation.…”
