Hello People,
I have to write a Code to detect ArUco Markers in an Image.
I already converted my Image into a binary image.
But now i dont know how to detect the markers on my Image.
Could need some quick ideas on that! thanks to all of u :)

Convert to grayscale using rgb2gray, threshold to binary black/white using imbinarize, label the connected components using bwlabel, then process the results. Maybe using imfill to help set all the pixels for each marker to white so that you can ignore their internal differences first.

Thanks for your reply.
I need to implement it like in this publication (4. Page 5-7)
