Hi, thanks for your great work.
I’ve got one problem. I’ve seen a version of ROI Align, one of whose parameters is the spatial_scale, representing the scale to map the feature coordinate to the original image. For example, if the original image is 224x224 and the feature map is 14x14, then the spatial_scale is 16.
In your version of ROI Align there is no such parameter. So I guess the ROIs being fed to this function should be scaled before hand, e.g., they should be divided by 16 in the example above. Am I right?
