Solving the image search problem


I was wondering if there's a way to search an image by uniquely identifying its contents. At present, the search engines rely on the tags & other textual metadata.

I've few ideas, but I'd like to listen to yours first. This could also be an interesting project and an idea for a startup! ;-)

    You could find out the boundary of all the shapes in that image, find out similar shapes from an existing library of basic shapes and do pattern matching.

    Ah yes, edge detection for finding the shapes could work!

    Other than shapes, colour data can be useful too. I saw on Deviant Art where they have this palette thing to find other images with similar colours.

    and more usual method...Content Based Image Retrival (CBIR)..but i think success percentage is low around 40-45%

    What is CBIR?
    where you extract a feature vector from a image and search Database to search images with similar feature vectors.....

    Funnily enough, all the searches we discussed as yet, involve finding a particular type of metadata, and searching in that metadata!!

    Is there another method where no metadata has to be generated?
