Single upper limb pose estimation method based on improved stacked hourglass network

no code implementations16 Apr 2020 Gang Peng, Yuezhi Zheng, Jianfeng Li, Jin Yang, Zhonghua Deng

Using the stacked hourglass network model, a single-person upper limb skeleton key point detection model was designed. Deconvolution was employed to replace the up-sampling operation of the hourglass module in the original model, solving the problem of rough feature maps.
