Human body key point detection algorithm is one of the important technologies in the field of computer vision. It can accurately detect key points of the human body in images or videos, such as head, shoulders, elbows, wrists, knees, ankle joints, etc. By identifying and tracking these key points, the algorithm can achieve accurate recognition and tracking of human posture, and has broad application prospects. In order to train and evaluate the performance of these algorithms, researchers constructed a large number of human key point detection algorithm data sets. These data sets contain human body images and annotation information under different postures, lighting and background conditions, providing a basis for algorithm training and testing. The human body key point detection algorithm has important applications in the fields of human-computer interaction, action recognition, motion analysis, etc.
1. Data set
Human body The data set of the key point detection algorithm is the data set used to train and test the algorithm. There are currently several public datasets available, here are a few representative datasets.
1.COCO data set
COCO data set is one of the most commonly used and widely used human key point detection data sets. Contains more than 200,000 images, each of which is annotated with key points of the human body. The advantage of the COCO data set is that it has high image quality, accurate annotation, and covers a variety of complex scenes and postures, making it suitable for training relatively complex human body key point detection algorithms.
2.MPII dataset
The MPII dataset is a multi-person dataset containing human poses, containing more than 25,000 images, each Each image has key points of the human body annotated, most of which are single poses. The advantage of the MPII data set is that it contains a large amount of single-person pose data and is suitable for training single-person key point detection algorithms.
3.PoseTrack data set
The PoseTrack data set is a data set for multi-person posture tracking tasks, including multiple action sequences. Covers a large amount of multi-person pose data and provides tracking annotation information. The advantage of the PoseTrack data set is that it provides annotation information for multi-person key point tracking and is suitable for training multi-person key point tracking algorithms.
4.AIC data set
The AIC data set is a human action and behavior recognition data set released by the Institute of Automation, Chinese Academy of Sciences, including It has collected more than 16,000 high-quality images, each of which is annotated with key points and movements of the human body. The advantage of the AIC data set is that it provides richer annotation information and is suitable for training key point detection and action recognition algorithms.
The above data sets are all public and can be downloaded and used on the corresponding websites. Using data sets for algorithm training and testing is an important basis for research on human body key point detection algorithms.
2. Application
The human body key point detection algorithm has many applications. The following are some representative applications:
1. Posture estimation
Human body key point detection algorithm can be used for posture estimation, that is, identifying the key point positions of the human body from images or videos, and then Inferring the posture of the human body, such as standing, walking, running, etc., can be applied to sports analysis, health management and other fields.
2. Action recognition
Human body key point detection algorithm can be used for action recognition, that is, identifying the key points of the human body from images or videos Point positions and action types can be applied to human behavior analysis, intelligent monitoring and other fields.
3. Posture tracking
Human key point detection algorithm can be used for posture tracking, that is, tracking the key point positions of the human body in real-time in the video and posture changes, which can be applied to fields such as virtual reality and game development.
4. Human body interaction
The human body key point detection algorithm can also be used for human body interaction, that is, by detecting human body key points to achieve interaction with the human body Interaction, such as gesture recognition, expression recognition, etc., can be applied to smart homes, smart robots and other fields.
5. Human body safety
Human body key point detection algorithm can also be used for human body safety, such as pedestrian detection, face recognition, etc. Used in security monitoring, people flow statistics and other fields.
The above applications are just the tip of the iceberg of human body key point detection algorithms. With the continuous development of technology, the application fields of human body key point detection algorithms will become more and more extensive.
In summary, the data set and application of human body key point detection algorithms are important components of the research and application of human body key point detection algorithms. The selection and use of data sets have a crucial impact on the training and testing of algorithms, and the diversity and breadth of applications also demonstrate the huge application potential of human key point detection algorithms.
