Hello
Look at this chart please, can RM analyze sequence of images like this? ( each square has an image and they have a sequence like matrix)


Thank you in advance

    Hello @mbs,

    I would definitely take a look at imagemagick to process the images (resize, cut, etc...), put these into folders and use some more magic to transform the image into something texty.

    ImageMagick is a command line tool you can invoke with the Execute Program operator.

    Hope this helps,

    Rod.

    I can.

    Look at this chart please, can RM analyze sequence of images like this? ( each square has an image and they have a sequence like matrix)

    Well... basically all images are glorified sets of numbers. I can make an icon with the German flag with something like this:

    (0,0,0) (0,0,0) (0,0,0)
    (221,0,0) (221,0,0) (221,0,0)
    (255,206,0) (255,206,0) (255,206,0)

    Most analyses as neural networks, however, don't make use of a matrix. Instead, a neural network (I'm not entering into details about convolutional neural networks here) asks for an input like this:

    (0,0,0) (0,0,0) (0,0,0) (221,0,0) (221,0,0) (221,0,0) (255,206,0) (255,206,0) (255,206,0)

    Therefore if by "sequence" you mean "how much are images changed", then I would invent something with time series and the set of numbers or something similar. (This is just an invention).

    This means that RapidMiner can analyse images but it all depends on what do you need to do with these. The thing is that RapidMiner doesn't have a way to import/export images as content, to the best of my knowledge at least, so you need to decode those into numbers, probably using Python or something that can help you do the destructive part.

    All the best,

    Rod.

    If this is image processing, then probably you would need to do something with the Deep Learning extension and putting together different layers for taking the windowing as shown in the diagram.

    @Telcontar120

    Thank you for the answer.
    yes exactly but the problem is sequences!!!! can RM read that like matrix?

    I am definitely not an expert in the capabilities of the current DL extension. @pschlunder is probably better positioned to answer your question.

    For this project I have a lot of images ( like previous screen shot), what is your suggestion for gathering all of them in one place to make a data base?

    thank you
