如何用自己数据集测试（How to test with my own dataset.）

[clttyou]

I want to be able to test with my own dataset. First, I need to convert the image to. Mat, such as a_ x2.mat ,a_ x4.mat
In the project, for example, How is the file baby_ GT_ x2.mat generated?

我希望能用自己的数据集测试，首先需要将图片转换为.mat,如a_x2.mat ,a_x4.mat
请问项目中例如baby_GT_x2.mat的文件是如何生成的？
