Metrics calculation

[macsmy]

Hi,
What is the metrics calculation strategy for values you have provided in the paper?

• image, gt resized to 512x512?
• metrics calculation performed for 512x512 output, gt?
• output, gt values between 0-1?

Thanks for the dataset!

Hi, thanks for your attention.

for your questions:
Q1: image, gt resized to 512x512? metrics calculation performed for 512x512 output, gt?
Nope. The original image size is used when calculation metrics.
During training, we composite the image of size 512x512 as the input.
During validation, we resize the short side to 512 (with original width/height ratio) as the input. Then we upsample the predicted alpha matte to the original size and then calculate the metrics.

Q2: output, gt values between 0-1
Yep. All pixel values are between 0-1 during the metrics calculation.
