How did you get "min_sizes" and "variance" in config.py?

Dear @biubug6,

Deeper to anchor boxes, I got stuck as min_sizes and variance parameter in config.py.
Except the "steps" values, I understand it came from size of FPN. But how can you get the values of "min_size" and "variance" liked:

Face-Detector-1MB-with-landmark/data/config.py

Lines 4 to 6 in 2b07565

	'min_sizes': [[10, 20], [32, 64], [128, 256]],
	'steps': [8, 16, 32],
	'variance': [0.1, 0.2],

Face-Detector-1MB-with-landmark/data/config.py

Lines 24 to 26 in 2b07565

	'min_sizes': [[10, 16, 24], [32, 48], [64, 96], [128, 192, 256]],
	'steps': [8, 16, 32, 64],
	'variance': [0.1, 0.2],

Face-Detector-1MB-with-landmark/data/config.py

Lines 40 to 42 in 2b07565

	'min_sizes': [[10, 16, 24], [32, 48], [64, 96], [128, 192, 256]],
	'steps': [8, 16, 32, 64],
	'variance': [0.1, 0.2],

Does that parameter follow some kind of formula or something?
Hope to have your response!
