Hello All,

 

I am trying to run a simple viola jones algorithm for detecting human eyes in the images using RapidMiner's Fast Haar Detector operator. 

But, unfortunately I'm getting error like,

 

Exception: java.security.AccessControlException

Could somebody please help me in solving this??

    hello @royapurba007 welcome to the community. Unfortunately that image processing extension is VERY old, rather buggy, and not currently supported. Hence I am not surprised at all that you're getting error messages.

     

    However I believe that my friends in RapidMiner Research are playing around with this to see how it can be improved. I'm tagging my friend @pschlunder in hopes he can chime in...

    Hi @royapurba007,

    the extension is a bit older and still uses an older way of performing parallelization, and it looks like the error is caused by that. Try disabling the "parallel process" option and check if it works afterwards and please let me know.

     

    Regards,

    Philipp

    Hello @pschlunder,

     

    Unfortunately, It's throwing the same error even after disabling the parallel processing option!!

    Hi @royapurba007,

    I'm sorry to hear that. I'd like to look into the code to provide more information or a potential solution, but right now I don't have access to it, since the extension is not developed by us. I might be able to get access but this might take a while.

     

    But there is one more thing you can try: If you have a large license (or I guess the trial license for Auto Model should also work) you grant extra permissions to unsigned extensions in the RapidMiner settings, as displayed in the following screenshot:

    Make sure to apply the changes and restart Studio after checking the "Grant additional permissions" option.

    Is there any solution for an educational licence?

    It was supposed an educational licence there has no limitations, but I cannot grant permisions to unsigned extensions...

    :(

    hello @xesuspablo_gonz - so just to be clear, educational licenses do indeed have limitations. Please see our information page here: https://rapidminer.com/educational-program/
