Κάθε φορά που ανεβάζετε μια φωτογραφία στο Facebook ή σε κάποια άλλη από τις υπηρεσίες της εταιρείας, προστίθενται αυτόματα ετικέτες ή tags. Ένας από τους λόγους για αυτή την προσθήκη είναι ότι τα tags μπορούν να βοηθήσουν τα άτομα με problems vision to understand photos posted on Facebook (according to the company).
But the fact shows how much the algorithm has developed on Facebook. Needless to say, each tag or tag is automatically added to the bigger social networking data.
And while Facebook's image recognition algorithm continues to evolve to improve existing services, such as search or ensuring that pictures do not violate the social network's policies, and may add information that is not part of the image's metadata.
The algorithm that analyzes images in Facebook adds more basic tags like sky, tree, cat, and other words that define the image.
Since April 2016, Facebook automatically adds the alt tags to the uploads you upload, so they are filled with keywords that represent the content of your images. Your images are highlighted by Deep ConvNet developed by Facebook FAIR team.
If you're interested in learning how and which labels Facebook adds to your photos, you can install a browser add-on that reveals them.
The Show Facebook Computer Vision Tags is a browser add-on for him Chrome and Firefox. After installation, all you need to do is visit Facebook. You will notice that in the photos on the social network you can also see the labels in the top right corner.
Tags are only in the photos uploaded by someone and not in the images added with a link.
The images you see and do not have labels are because Facebook's image recognition algorithm has had trouble locating the image.
It seems that the algorithm does not work properly for all the images and definitely keeps Facebook's technicians busy. But as you will notice, he does his work for most of the photos on the website.
