Choose Function to Visualize Detected Objects

Computer Vision Toolbox™ offers several functions to visualize detected objects by inserting or overlaying shapes on image, video, and point cloud data.

The insert-related functions draw shapes and text by fusing them with image and video data. The showShape function uses MATLAB® graphics to overlay shapes and text on top of image, video, and point cloud data and is rendered in a MATLAB axes.
