Image Skeleton Recognition Methods

OpenPose
An open-source library for multi-person pose estimation. It detects key points on the human body, including joints and skeletal connections, using deep learning techniques with convolutional neural networks (CNNs). 

DeepPose
A method proposed by Microsoft that uses deep learning for estimating key points on the human body. It employs CNNs for end-to-end pose estimation by directly predicting joint positions from images.

PoseNet
Developed by Google, PoseNet is a lightweight real-time pose estimation system. It uses CNNs to detect key points on the human body and is suitable for applications requiring real-time performance. HRNet (High-Resolution Network)
An advanced pose estimation method that focuses on high-resolution feature representations. It maintains and merges multi-scale feature maps to improve the accuracy of key point detection. 

AlphaPose
An open-source multi-person pose estimation library based on PyTorch. It uses CNNs and confidence maps to detect key points and supports both single-person and multi-person pose estimation. 

MPII Human Pose Dataset
A widely used dataset for training and evaluating pose estimation models. It contains images with various poses and environments, suitable for training deep learning models. 

Stacked Hourglass Network
A design for human pose estimation that stacks Hourglass modules. It operates at multiple scales, making it suitable for different body sizes. 

Detectron2
Developed by Facebook AI Research (FAIR), Detectron2 is a general-purpose framework for object detection and instance segmentation. It can be used for detecting key points on the human body. 
 
LEAP (Learning Articulated Occupancy of People)
A method for 3D human pose estimation that predicts joint positions by regressing articulated occupancy maps. 
 
EfficientPose
A lightweight pose estimation method designed for real-time performance, using a combination of lightweight network structures and model compression techniques. 
 
Integral Human Pose Regression
This method regresses integral heatmaps for entire human body pose detection, with each heatmap corresponding to a joint's position. 
 
SimpleBaseline
An effective yet simple pose estimation method that stacks Hourglass modules at different scales and connects key points with a simple baseline. 
 
DeepLabCut
An open-source framework based on deep learning for pose estimation and behavior analysis. It provides a toolchain for training and evaluating custom models. 
 
MultiPoseNet
A framework for multi-person pose estimation that can simultaneously detect key points for multiple individuals. It uses cascaded convolutional network structures suitable for multi-person scenarios. 
 
HMR (Human Mesh Recovery)
HMR is a method that achieves human body pose estimation and reconstruction by mapping images onto a three-dimensional human body mesh. It focuses not only on key points but also provides an estimation of the entire human body shape. 
 
HRNet-3D
HRNet-3D extends HRNet to perform three-dimensional pose estimation. It enhances modeling capabilities for deep details by jointly optimizing two-dimensional and three-dimensional information. 
 
SPIGOT
SPIGOT is a method for human body skeleton estimation that leverages information from image semantic segmentation to improve the accuracy of key point detection. 
 
PifPaf
PifPaf is a method for jointly detecting human body key points and poses. It enhances overall model performance by simultaneously handling multiple tasks.
