string traindata_address = "....."

Then uncomment the fs save code at the first time!

 /*
    ////using trainingdata
    Mat traindata [36];

to

//////File save 

the pushback values (sign) must match the picture, and need to be transfer into int type as well.Last,pushback the image data simultaneously.

Don't forget to comment out if it's done.

if you want to use mine just run it.

remember to comment out the code from

 /*
    ////using trainingdata
    Mat traindata [36];

to
