CBIR or Grouping Similar Images

Does LeadTools have any functions to help with content based image retrieval, or the ability to group similar images together into clusters?


We need to take a list of document images and do a sort of quick sort on them to group similar images together.


There seem to be plenty of papers about this on the internet, but they all involve libraries I am not familiar with.


Some of the methods I have read about include the following:
Key point extraction and comparison.
Creating a saliency map to generate regions of interest and then doing feature vector comparisons.
Histogram comparisons.
Probably most interesting to me is this paper:
<elementary features paper>.
Can you guys point me in the right direction and perhaps tell me if the LeadTools toolkit can help me with this.

We do not have a general matching algorithm similar to what you're describing. If you want to retrieve specific information from images, such as their histogram or other attributes, this can be done with LEADTOOLS. However, if you want a general function that tells you if 2 or more images are "similar" in the broad human-like sense of the word, I'm afraid we don't have such a feature.
