Networks configurations. Each configuration is a different combination of input size, cost function, and sampling strategy. The low-resolution configurations have names starting with LR, and the high-resolution with HR. The cost function is reflected in the name as “w” for weighted cost function and “nw” for nonweighted. Finally, the sampling strategy adds “b” or “r” to the name, for balanced and random, respectively.

Name	Input size (pixels)	Cost function	Mini-batch sampling strategy
LR-w-b	$640\times 512$	Weighted MSE	Balanced by VAS ranges of 20
LR-nw-b	$640\times 512$	MSE	Balanced by VAS ranges of 20
LR-w-r	$640\times 512$	Weighted MSE	Random
LR-nw-r	$640\times 512$	MSE	Random
HR-w-b	$1240\times 1024$	Weighted MSE	Balanced by VAS ranges of 20
HR-nw-b	$1240\times 1024$	MSE	Balanced by VAS ranges of 20
HR-w-r	$1240\times 1024$	Weighted MSE	Random
HR-nw-r	$1240\times 1024$	MSE	Random
