Multi-scale Attention Aided Multi-Resolution Network for Human Pose Estimation

In this paper, we propose attention maps at various scales on multi-resolution feature extractor baseline network for human pose estimation. The baseline network captures information across various scales with the help of repeated bottom-up and top-down approach using successive pooling and up-sampling. We propose a network named Refinement Net for regressing the predicted heatmaps to 2D joint locations to remove ambiguities in predicted position. We experiment with three levels of attention schemes - global, heatmap and multi-resolution. Attention masks helps in generating basin of attraction that helps the network on deciding where to "look". The proposed network performance is at par with the state-of-the-art two dimensional pose estimation methods on MPII dataset.
