如何区分数据集中的合成数据集和真实数据集？

[shenshanf]

Dear authors,

I am currently working with the UAVStereo dataset for my research on stereo matching in UAV scenarios. While studying the dataset, I noticed that the distinction between synthetic and real data subsets is not clearly specified in the dataset description or the accompanying paper.

Could you please clarify the following points:

1. Does the UAVStereo dataset contain both synthetic and real data subsets?
2. If so, how are these subsets distinguished within the dataset structure?
3. Are there any specific naming conventions or directory structures that indicate which images are synthetic and which are real?
4. In the sample distribution table provided in the paper, do the numbers for Residential (R), Forest (F), and Mining (M) include both synthetic and real data, or do they represent only one type?

Your clarification on this matter would be greatly appreciated and would help researchers like myself to better understand and utilize the dataset.

Thank you for your time and for providing this valuable resource to the community.

Best regards, Jian Deng
