normalization

[XIDIANPQZ]

Hello, excellent work! I have a question regarding data preprocessing that I find a bit confusing. When processing the Human3.6M dataset (as seen in the following code: link), the values are normalized to the range [-1, 1]. However, during the preprocessing for "infer-wild" (referenced here: link), the scale is determined by the smaller dimension of (height, width). This results in a range that can exceed 1.

I’m wondering if this discrepancy in scaling could have an impact on the results. Could you clarify this?
