The evaluation instruction in the Simple Track has been updated. Please check for details.

 

In the Simple Track, there are other value besides 0 and 255 in the ground truth.

That is because in the making of dataset, image binarization was finished first, and then sampling via bilinear interpolation was conducted. In fact, Nearest Neighbor should have been adopted as the sampling method. In evaluation, ground truth was binarized first (threshold value: 122) before the process. we sincerely apologize for the mistake.
