Mismatch between paper and code

I can see from paper that size for template's features should be 15x15x256, but because of [this](https://github.com/foolwood/SiamMask/blob/master/experiments/siammask_sharp/custom.py#L21) condition actually it is 7x7x256. Can anyone explain?

Start with experiments/siammask_sharp/custom.py at line 21 and compare its condition with the paper's stated 15x15x256 template feature size. Trace how that condition produces the reported 7x7x256 size. Done means documenting whether the implementation is intentional or identifying a concrete discrepancy.
