Improved Actor Relation Graph based Group Activity Recognition

1 code implementation • 24 Oct 2020 • Zijian Kuang, Xinran Tie

We propose to use Normalized cross-correlation (NCC) and the sum of absolute differences (SAD) to calculate the pair-wise appearance similarity and build the actor relationship graph to allow the graph convolution network to learn how to classify group activities.
