Match an image to a bank of pre-existing images (OpenCV, SURF, Python)

Hello, I'm looking for solution to match an image to a bank of pre-existing images.

My problem is to manage large numbers of images (scan documents) and detecting duplicates.

How I'm going to test it:

1) add image to bank (database) -- return id, name

2) remove image from database -- delete image from database by id

3) match(search) new input image with database, return list of matches - id, name and similarity in %


1) able to support up-to 100,000 images

2) response time not over 1 sec for 10,000 images, and 5 sec for 100,000 images in database

3) in case of the document will be sent as a photo (made with the mobile phone camera), you must perform an operation consisting in ability find the contour (outline) representing the piece of paper being scanned

Similar solution is here: [login to view URL] but it is too slow (very very slow)
