The scales are expressed in terms of pixel widths in the input image. See this comment for more details.
For a new dataset, I would start with the current scale range, then update it if the Gaussians seem too large or small on average. Defining the scale in terms of pixel widths is supposed to make the scales invariant to image resolution, but I suspect that larger images will require larger max scales, since it can be helpful to have large Gaussians even for high-resolution images.
