Pose estimation is the process of determining the position and orientation of an object, typically a human body, in an image or video. It involves analyzing the image to identify key points or features, such as joints or other anatomical landmarks, and then using mathematical algorithms to estimate the position and orientation of the object. Pose estimation is a specialized skill that is used in a variety of applications, including robotics, augmented reality, and motion capture. It requires knowledge of computer vision and machine learning techniques, as well as a deep understanding of human anatomy and movement.
