For convolutive degradations:

• '-degrad_train' == {'type': 'B', 'min_sigma': 0.2, 'max_sigma': 2.6}
• '-degrad_test' == [{'type': 'B', 'sigma': 1.3}] # for evaluation.

For additive degradations:

• '-degrad_train' == {'type': 'N', 'min_sigma': 0, 'max_sigma': 30}
• '-degrad_test' == [{'type': 'N', 'sigma': 15}] # for evaluation.
