hello @595972434

If you imshow your data transformed in matlab, you will find all of them are actually normal.

1. As for the 'invalid poly' errors, this is because some of your origin images are too small.
   For more details, please see <Data-set formating and small area of polygon #79>.

2. As for the 'poly in wrong detection' errors, many other people find that no matter how you pre-process the images, some little 'poly in wrong detection' errors will still occor.
   For more details, please see <Poly in wrong direction during training on the Cursive Text (Written from right to left) #104>.

So don't worry.

After you have run <transform.m> to pre-process ICPR2018, please just continue training.
