aAcc indicator == pixel accuracy ?

[rouchoo]

hi, i want to figure out that the calculation formula of aAcc indicator, which is used in validation.

i saw the aAcc function state that : aAcc = interaction of prediction and label area / label area.

However i can hardly get some useful information about aAcc on the Internet. i just feel aAcc is similar to pixel accuracy(PA). So i ask for your help. Thanks!

Best regards.
