element-wise label size is 15*15 in the code while 17*17 in the paper #26

In siamese-fc paper, after cross-correlation layer, the output is a 1717 array which means that the element-wise label should be a 1717 array too. But in the released code, I found out that the element-wise label size is 15*15. It's quite confused.

The score map (and element-wise labels) has size 17x17 for a search region of size 255 pixels. However, to enable data augmentation, we instead use a search region of size 255-2*8 = 239 pixels. This reduces the size of the score map to 15x15, since the score map has stride 8 with respect to the search region.

Got it. Thanks a lot ~
