About the LS3D-W annotation

Hi, thanks a lot for your project!

I want to use your LS3D-W dataset as my training set. But when I get access to the .t7 annotation file, I get the 68*2 array, instead of 68*3 with depth dimension as I expected.
So, this dataset contains 3D landmarks, right? Where could I get the depth dimension?

Thanks you very much!

該 issue 關於 LS3D-W 資料集的標註格式。使用者期望一個 68x3 的陣列，但發現是 68x2。檢查資料集載入程式碼和文件以理解標註結構。尋找處理 .t7 檔案的腳本，查看深度資訊是否儲存在其他地方或需要推導。透過查閱論文或 README 來驗證資料集的預期格式。
