    Hi,
    official homepage of extension developers is http://spl.utko.feec.vutbr.cz/en. But work on documentation and tutorials is still in progress. If you have some questions, you can write it here or if you need profi support, contact developers.

    Regards

    Hi, Vaclav,
    I know nothing about image data mining, but I would like to know your opinion - is image mining extension suitable for some analysis of the aerial photos - e.g. identification of the land use, maybe also other things...?

    Hi,
    I don't know, how images looks like and what you want to detect. For example you want detect water, filed and urban, than I think, it is suitable. For more difficult or special task will maybe be needed new feature extraction operators...

    There are few general steps which you must walk through:

    1) preprocessing - histogram normalize, resize, denoising etc.
    2) create mask - manually select regions which you want to detect
    3) generate example set - get features from segment or points + label from mask
    4) train model - maybe some optimizations...
    5) test model

    Dear BK,
    I can only agree with the lack of manuals on image processing topics using rapidminer. I know, this is very time consuming. A solution could be to publish more project examples related to this topic on myexperiment or similar sites. I hope the message wil be read by those colleagues.
    Success

    Hello,
    I post few examples on http://www.myexperiment.org/users/18932/workflows. I will add some more later. If you have special request, you can write it here...

    Best
    Vaclav
