Traditional 2D human pose estimation methods use different hand-crafted feature extraction techniques for the individual body parts.Įarly computer vision works described the human body as a stick figure to obtain global pose structures. What is 2D Human Pose Estimation?ĢD human pose estimation is used to estimate the 2D position or spatial location of human body keypoints from visuals such as images and videos. Since pose motions are often driven by some specific human actions, knowing the body pose of a human is critical for action recognition. Human pose estimation aims at predicting the poses of human body parts and joints in images or videos. With real-time human pose detection and tracking, the computers are able to understand and predict pedestrian behavior much better – allowing more natural driving.Įxamples of pose predictions on sports, professional and casual photos from the CrowdPose set. Today, the majority of self-driving car accidents are caused by “robotic” driving, where the self-driving vehicle conducts an allowed but unexpected stop, and a human driver crashes into the self-driving car. This will have a big impact on various fields, for example, in autonomous driving. For example, tracking the human pose in real-time will enable computers to develop a finer-grained and more natural understanding of human behavior. High-performing real-time pose detection and tracking will drive some of the biggest trends in computer vision. However, conventional pose tracking methods are neither fast enough nor robust enough to occlusions to be viable. By performing pose detection and pose tracking, computers can develop an understanding of human body language. In traditional object detection, people are only perceived as a bounding box (a square). Top-down methods run a person detector first and estimate body joints within the detected bounding boxes.Bottom-up methods were pioneered with DeepCut (a method we will cover later in more detail). Bottom-up methods estimate each body joint first and then group them to form a unique pose.Top-down methodsĪll approaches for pose estimation can be grouped into bottom-up and top-down methods. Hence, state-of-the-art methods are typically based on designing the CNN architecture tailored particularly for human pose inference. Today, the most powerful image processing models are based on convolutional neural networks (CNNs). With the latest advances, new applications with real-time requirements become possible, such as self-driving cars and last-mile delivery robots. The performance of semantic keypoint tracking in live video footage requires high computational resources what has been limiting the accuracy of pose estimation. Examples of semantic keypoints are “right shoulders,” “left knees,” or the “left brake lights of vehicles.” Human pose estimation and tracking is a computer vision task that includes detecting, associating, and tracking semantic key points. Use Cases and pose estimation applications.Different variations: Human pose estimation, head pose estimation, animal pose estimation.This article provides an easy-to-read guide about the latest pose tracking methods in AI vision. As a field of artificial intelligence (AI), computer vision enables machines to perform image processing tasks with the aim of imitating human vision. Pose estimation is a popular task in Computer Vision.
