the point of 'sub_pixel_locating_factor'

[ningdan]

Dear Yanzhao,
Sorry to bother but I have some issues when running the code. In the paper, there is a description as "We first upsample the class response maps to the size of the image via bilinear interpolation." However, in the code , the size of upsampling class response map is 112*112. It doesn't match the above description for the input image is of size 448 * 448. And I don't understand the meaning of the parameter sub_pixel_locating_factor.
Hope for your reply.
