although I'm not quite sure if this forum also provides support for the mentioned extension I decided to ask my question here anyway:
I installed the Image Mining Exentsion
according to the instructions by moving the jar file to "RapidMiner5->lib->plugins" and most of the Operators for Image Processing seem to be okay. When looking at the Extension Manager in RM5 I noticed that the extension is not listed there, which I already didn't take for a good sign.
While trying to wrap my head around image mining in RM5 I stumbled upon this image
that showed a process I wanted to recreate - then I noticed I am missing the operators 'List images", 'upload images' etc.
Can someone tell me where I went wrong?
