[Bug]: Fhog_example does not work with example data

[TonyCongqianWang]

What Operating System(s) are you seeing this problem on?

Linux (x86-64)

dlib version

19.24 51c7a3597935ed2cb969521a0ada0b7209f78ec2

Python version

N/A

Compiler

GCC 9.4.0

Expected Behavior

I compiled the example programs and tried to ran the ./fhog_object_detector_ex ../faces that worked. But when I removed the "optional" upsampling, I get an exception that there was an impossible box. To me it it should be possible to run the example program even after removing the "optional" code.

Current Behavior

Exception is thrown "impossible box detected".

Steps to Reproduce

clone current repo, build examples, comment out the lines

upsample_image_dataset<pyramid_down<2> >(images_train, face_boxes_train);
        upsample_image_dataset<pyramid_down<2> >(images_test,  face_boxes_test);

in fhog_object_detector_ex.cpp and run with ./fhog_object_detector_ex ../faces

Anything else?

No response

Thanks, yeah those comments are not clear, since for that dataset upsampling is required. I just updated them to be less confusing.
