Hi

Hi,
   I wonder if anyone has ever seen/found anything on 2D wavelets for image processing(not compression) in Delphi?
I dont seem to find anything, If I google then one of my top hits is the request I made in 2001 :-)
I could look to translate but wondered if there was anything I could purchase etc...
Also on a related topic has anyone started to use OpenCV via Delphi XE7?

Kind regards
Adrian

    No challenge, no fun! :-)

    All true - but I have other coding things to work on - and doing something new is even more fun :)

    By the way, on topic, Adrian knowles do you want to implement something in Delphi? There are lots of C examples of basic FFT code, for example, which would be easy to translate to Delphi. Wavelets too, although when I wrote the one I mentioned above, the author of the paper I was working from had published Matlab code implementing the specific wavelets, and I used that as a reference when converting to C++. You could do the same, just to Delphi.

    Hi everyone,
        thanks for all the stimulating comments!

    I think you are right +Richard. OpenCV seems to be the best 'ready made approach' I can find.
    I have just struggled to get it installed correctly on my last attempt but will try again.

    Although Mitov does not have a wavelet algorithm they have other interesting things in this particular area, image feature detection.

    Lohniger(?) sw has a 1D wavelet which could be used at a pinch I believe, apply it in both directions(X and then Y) and then combine the results.

    Imageen is a great Delphi image processing library which I use a lot. It supports FFT but nothing as exotic as wavelets

    My principal interest is exploring different image analysis methods for the classification & detection of anatomy in MR images.

    Unfortunately my desire to explore is not matched by my Delphi skills :-)

    I'm an amateur at best and programming is not my principal job.
    I just got frustrated by the lack of sw developers I had access too at work and decided to do some of it myself in Delphi (first learnt in '97 then stopped using for 10 years until 2012) .
    I discovered just how fast I could develop a proof of concept in Delphi compared to some of the other languages/tools the sw teams had access too. 

    So my hope was that I would find a dedicated component but as you mention David I will probably bite the bullet and try and translate one of the C examples :-)

    Thanks again everyone!
    Adrian
