Scientists are trying to create technology that would let you disappear in an instantĪ true cloaking device would need to find a way to bend light around a person or object from all directions. However, do not lose hope! Some research and prototypes out there could actually bring an invisibility cloak to market sooner than you think. Finding the most viable and useful option is tricky. In fact, not only is it difficult to create, there are many different ways to make something invisible. In case of any questions, please reach out to us at 2021 The MathWorks, Inc.The technology is far from perfect.

Replace the contents of the respective MATLAB Functions blocks (i.e.Open the the Simulink model Invisibilit圜loak.slx.Use Image Segmenter App to refine the mask exported from the Color Thresholder App.Export the output as a Function and as Images. Use the foregroundImage using 'Load Image from the Workspace' in the Color Threshodler App and threshold for the required mask. Run the Foreground Setup section of the startScript.mlx file.Do not include yourself or the cloack in this image. Ensure to have only the stationary background in this image. Run the Background Setup section of the startScript.mlx file.Ensure the correct camera is selected and run the Camera Setup section on the script to initiate the camera.The demonstration needs a stable background without any moving objects in the camera frame except the cloak. Note: The startScript.mlx file needs to be run if the camera placement is changed.

Invisible cloak code#

This is a one-time setup code as long as the placement of the camera, or the background, or the lighting does not change.

This has to be used to capture the background image and the color of the foreground cloak. StartScript.mlx contains the MATLAB code for the initial setup of the model. Use the MATLAB Function outputs from the Color Thresholder App and the Image Segmenter App in the respective MATLAB Function blocks in the model. Invisibilit圜loak.slx contains a model which implements the invisibility cloak. The mask that contains the colored cloak will use the backgroundImage and the part of the video that does not have the colored cloak use the original video feed.Multiply the binary complement of the mask with the input video to display the video stream for the rest of the image.Multiply the thresholded mask to the background image to display the background in the colored cloak area giving an illusion of invisibility.Use the MATLAB Functions exported from the mask to create a threshold mask and refine the thresholded mask using Image Segmenter App.Open Color Thresholder App and move the sliders to detect the color of the cloak and differentiate it from the background.Capture an image of the colored cloak (cloth) in foreground using a camera connected to the system.Save the image on the workspace as backgroundImage.Capture an image of the stationary background from the web camera connected to the system.The model showcases the workflow of using the Image Thresholder App and the Image Segmenter App to create the illusion of an invisibility cloak.
