Scan images to recognize objects in them

This request is clear and relevant.

I would like to get PHP Classes for the object recognition from images.

I have a large database of 90,000 images on the server and I need to match them by taking a picture from the camera using iPhone App.

I need to recognize the image and then take the objects out.

After that it will compare with the object to get the exact match.

    That is a good question.

    There is a PHP class that can recognize text in images.

    There is also a PHP class that can recognize nudity in pictures.

    But to recognize arbitrary objects in images I do not know anything.

    Do those objects have specific characteristics that may facilitate the detection by an eventual algorithm?

      Yeah, it seems like he's requesting a computer vision algorithm here.

      There's a php implementation of opencv (A computer vision library), but it looks like a big learn most especially if the requester needs it urgently.

      It is possible to muddle one up but it may not "recognize image entities", as opencv would.

      Hi Manuel,

      Thanks for answering this Question, I really appreciate your help.

      Actually the Images are Product Images of a Company and we have to match it on server using PHP because of the Huge Database. Now we can either detect shapes Or objects from the database image as well as the uploaded image and then match them for exact image.

      I think that Shape Detection can also work, Do you know some Shape Detection Algorithm for PHP that can detect edges. Thanks

      Hi Samuel,

      Thanks for answering, It really helps. I have checked opencv as well but their wrapper doesn't seems to help much.

      Do you know some Shape Detection Algorithm and then Comparing those shapes for the right image. Thanks

      Yes, there used to be a package that could recognize face shapes using OpenCV data but for some unknown reason the author removed the package.

      Anyway, I think your problem is more generic and so it seems harder because you probably have many products of many shapes, some with similar shapes, which makes it hard to distinguish the problems just analyzing pictures.

      Maybe you should consider some other method to recognize the objects, maybe barcodes, I don't know if that would make sense.
