The idea is to detect objects in an image. Say, i have a book in a image and i would like to detect it. I read about the SURF algorithm but i don't think it would be applicable in my project. The object which is a book can be of any type and doesn't need to be in the database before. I will have a collection of images of book in my database and i have to create a recognizer file such that when i run a test image through my program, it can classify books from other objects. So, what could be my possible options?

The problem, as you have stated it, is one of the largest, most active areas of research in computer vision. OpenCV provides the cascade classifier. There's a tutorial HERE.

There are other options, like keypoint matching, but as you said, not quite what you're looking for.

Something interesting I found recently is THIS, which looks like it might actually work pretty well. Unfortunately, the OpenCV Implementation link is a lie, so you'd have to do the Matlab -> OpenCV conversion yourself.
