algorithm to calculate code for an image


I am working on a content-based image retrieval system on a distributed environment, I need an algorithm that takes as input an image and gives me a code for the image, this code should be such that it can be used to match visually similar images.


Solution

  • It depends on kind of images, one workable alternative would be invariant moments ( either hu, or zernike )

    We use this method in javaocr library, feel free to grab code from there.

    Main advantage of invariant moments with cluster mathing is that it provides distance from cluster centers ( like: this is 90% cucumber but 20% apple )
