Evaluation on Synthetic-Composite Adobe Dataset #75

Hi, thanks for the great work! The idea is really novel and the performance is amazing!

I have a question regarding the number reported in Table 1. in the paper. Based on Sec 4.1, "We computed a trimap for each matte through a process of alpha matte thresholding and dilation as described in [36]." Does it mean that you generate the trimap based on ground-truth alpha matte instead of using the trimap images provided in the dataset?

Besides, in Sec 4.1, "We rescaled all images to 512 × 512 and measure the SAD and MSE error between the estimated and ground truth (GT) alpha mattes." Does it mean the model in evaluated with 512x512 images, or only the score is calculated on the resized images? (i.e. The model is inferred on the original images or resized images).

I did not find the evaluation code relating to Adobe dataset, should I directly use the inference codes to reproduce your results?

Thanks really in advance!
