This Python script utilizes the Mediapipe library to perform multi-landmark tracking in real-time. It incorporates three main components: Pose Estimation, Face Detection, and Hand Tracking. The script captures video from the webcam, overlays detected landmarks on the face, hands, and human pose, and displays the result in a resizable window.

Press 'q' to exit the application.

• Pose Estimation: Tracks the human body pose.
• Face Detection: Detects and tracks faces in the video stream.
• Hand Tracking: Tracks hand landmarks and connections.

• Pose Estimation (mp_pose): Utilizes the Mediapipe Pose model to estimate human body pose, including landmark locations for various body parts.
• Face Detection (mp_face): Employs the Mediapipe Face Detection model to detect and track faces in the video stream. It extracts bounding box coordinates for each detected face.
• Hand Tracking (mp_hands): Uses the Mediapipe Hands model to track hand landmarks and connections. It provides coordinates for each hand landmark and visualizes connections between them.

• estimate_pose(frame): Estimates the pose landmarks in a single frame using the Mediapipe Pose model.
• estimate_face(frame): Estimates the face landmarks in a single frame using the Mediapipe Face Detection model.
• estimate_hands(frame): Estimates the hand landmarks in a single frame using the Mediapipe Hands model.
• draw_face_landmarks(frame, landmarks): Draws bounding boxes around detected faces on the frame.
• draw_hand_landmarks(frame, landmarks): Draws hand landmarks and connections on the frame using Mediapipe drawing utilities.
• draw_landmarks(frame, landmarks): Draws pose landmarks on the frame using Mediapipe drawing utilities.

• propagate_pose(prev_pose, current_pose): Propagates poses from the previous frame to the current frame. If the previous pose is not available, it returns the current pose; otherwise, it averages the previous and current poses.
• propagate_poses(frames): Propagates poses across frames. It estimates poses for each frame, propagates them based on the previous frame's pose, and visualizes face and hand landmarks.
