The problem it is about opencv Java. I have no idea how to fix this error. Because it works normally if i call this two method one by one but it's error when it is in the same method.

the link of java code and error picture is below

when i call method Threshold with bluecircle it will turn bluecircle to be the same as maskbluecircle is and then i just put them into matchtemplate.object method.

I will show you below how it works when i call method one by one:

object.png

then i call matchtemplate with object.png and maskbluecircle(actually it is the same)

So as I said it works when they are seperated. SO HOW TO COMBINE THEM IN THE SAME METHOD WITH OUT ANY ERRORS .If you produce me the sample code it would be really appreciate. THANK YOU.
