 Here you'll find some cool examples of what you can do with MARTINS.js. Simply click on a link or scan any of the QR codes below. After opening the web pages, scan the [target image](#target-image). In addition, please read the [guidelines](#guidelines).
 
 * If you're scanning the image on a screen, make sure to adjust the brightness. If the screen is too bright (too dark), it will cause overexposure (underexposure) in the video and tracking difficulties - details of the images will be lost. Screen reflections are also undesirable.
 * If you print the image, avoid shiny materials (e.g., glossy paper). They may generate artifacts in the image and interfere with the tracking. Prefer non-reflective materials.
