EfficientPose

The inference code of the paper EfficientPose: Efficient Human Pose Estimation with Neural Architecture Search

We propose an efficient framework targeted at human pose estimation including two parts, the efficient backbone and the efficient head. We use NAS(Neural architecture search) technology to obtain lightweight backbone. For the efficient head, we slim the transposed convolutions and propose a spatial information correction module to promote the performance of the final prediction.
