    Please take also a look to the brand new opencv common interface on pluggable descriptor detector:

    I have a question Amit. Thanks for your wonderful post btw.

    If i have 2 images and I get a list of vectors that match: what should be my test to say that the images closely match or not?

    Assume I want to match 2 images (an original source and another one that has beenc compressed or something).I get the point of interest from both the images ans compute the match vector. what next? what will tell me whether those 2 images are close or not?

    Thanks in advance

    What do you think that is better, OpenSurf or SURF implementation of OpenCV 2.2?

    Nice blog 🙂

      Well , I have not personally tried SURF implementation of OpenCV 2.2 , but I would definitely go for it.

    Hi Amit!
    I want to use open SURF for recognition in AR in iPhone.I don’t know how to get ModelView matrix of the object in camera frames. Please guide me that is there any utility function or any tutorial, code or book so that I could get the concept. Please guide me. Thanks a lot in advance.

    Amit

    Thanks for the wonderful discussion . I am working on a project which need to detect copy move image manipulation . I am using the c# version . In this project it is needed to match the features with the same image , if copy move has been done then it ca be detected . Please help me with how can i do features matching with a same image .

    Thanks and Regards
    Somu

    Hi, Amit
    I’ve run this open surf library using Visual Studio 2008 and OpenCV 2.0
    But ,, these errors are found
    ………………..

      Please check the latest openCV for newer object detection implementations.
