imgseek for image matching.

[Venkata Ramanan]

Hi,

I have a bunch of known images and their name. My objective is that given a new image in need to return the name of the image to which it matches or I should say 'no match'. 

I am evaluating imgseek for this. But imgseek just gives me results irrespective of whether it matches or not. I don't think that the percentage match that it tells makes any sense. For example for two same images it says matches 40%. 

Any idea how I could solve this problem? I have 1000s of images and imgseek at least does a good job of reducing the scope to 10 images. Please suggest me to a way (using imgseek or any other tools) to find out percentage similarity of two images which is reliable.

Thanks in advance.
