How does the coordinates were processed?

The image actually resized

We normalize the coordinates into [0, 1]. The Resize operation does not influence the normalized coordinates.

@SY-Xuan Hello, can the ratio be maintained? If not, will the image be distorted?

[SY-Xuan]

We find that maintaining the image ratio does not bring performance gains. So we did not preserve the image width/height ratio.

@SY-Xuan thanks for the reply, so that the image would be distored.

But you have used the coordinates according to original height and width, is that matchable? (think about it, the image could be shifted resized into a weired ratio, but the GT didn't changed)

[SY-Xuan]

The coordinates are normalized into [0, 1], which means they are not related to the original height and width. For example, [0, 100, 0, 100] with an image (1000 X 1000). The normalized coordinates are [0, 0.1, 0, 0.1]. We can resize the image to any size. The normalized coordinates remain unchanged.
