Description

This ROS2 package implements OpenCV to detect faces in camera images. It consists of the following ROS nodes:

• usb_camera_node: Receives image data from a USB camera and publishes it for processing.
• face_detect_node: Subscribes to the image data, determines the location of faces, and publishes new image data with a bounding box around each detected face.
• rqt_image_view: Displays the image data with bounding boxes drawn over each detected face.
