AI Can Figure out What You Look Like from Your Voice

The era of data-driven artificial intelligence has arrived. The quality of data directly affects the effectiveness and intelligence of the model. In this wave of technological change, datasets in various vertical fields are constantly emerging to meet the needs of machine learning in different scenarios. Whether it is computer vision, natural language processing or behavioral analysis, various datasets contain huge commercial value and technical potential.

Human Keypoints Detection, also known as human pose estimation, is a relatively basic task in computer vision and a pre-task for human action recognition, behavior analysis, and human-computer interaction. In general, human body key point detection can be subdivided into single/multi-person key point detection, 2D/3D key point detection, and some algorithms will track key points after completing key point detection, also known as human body. Attitude tracking.

The human body key point detection algorithm can be divided into 2D key point detection and 3D key point detection according to whether it contains 3D depth information. 2D key point detection started earlier and the research is more mature, but in recent years, 3D keypoint detection has attracted a lot of attention.

At present, the common human body key point recognition based on AI technology can generally estimate the information of 14 main key points of the human body in the video or picture, and some can realize the estimation of the coordinates of 16 key points and their visible information. Human body key point recognition mainly recognizes the positions of the human body’s eyebrows, nose, left and right elbows, left and right arms, left and right eyes, left and right ears, neck, left and right ankles, etc. Multiple postures such as standing, sitting, falling to the ground, and climbing movements are estimated, so as to realize the detection and recognition of action postures.

Human skeleton key point detection is one of the basic algorithms of computer vision, and it plays a fundamental role in the research of other related fields of computer vision, such as behavior recognition, person tracking, gait recognition and other related fields. The specific applications are mainly concentrated in intelligent video surveillance, patient monitoring system, human-computer interaction, virtual reality, human animation, smart home, intelligent security, athlete-assisted training and so on.

However, because the human body is quite flexible, various postures and shapes will appear, and a small change in any part of the human body will generate a new posture, and the visibility of its key points is greatly affected by clothing, posture, and perspective. Moreover, it is also faced with the influence of occlusion, lighting, fog and other environments. In addition, there will be obvious visual differences between 2D human body key points and 3D human body key points, and different parts of the body will have a visual shortening effect (foreshortening) , making human skeleton keypoint detection a very challenging task in the field of computer vision.
