Recognition Method with Deep Contrastive Learning and Improved Transformer for 3D Human Motion Pose

Abstract

Abstract Three-dimensional (3D) human pose recognition techniques based on spatial data have gained attention. However, existing models and algorithms fail to achieve desired precision. We propose a 3D human motion pose recognition method using deep contrastive learning and an improved Transformer. The improved Transformer removes noise between human motion RGB and depth images, addressing orientation correlation in 3D models. Two-dimensional (2D) pose features are extracted from de-noised RGB images using a kernel generation module in a graph convolutional network (GCN). Depth features are extracted from de-noised depth images. The 2D pose features and depth features are fused using a regression module in the GCN to obtain 3D pose recognition results. The results demonstrate that the proposed method captures RGB and depth images, achieving high recognition accuracy and fast speed. The proposed method demonstrates good accuracy in 3D human motion pose recognition.
