Details of the network architecture (LSTM) for identifying closely-spaced landmarks. Gnathion (Gn), Pogonion (Pg), B Point (B), and Infradentale (Id) are determined once the Menton (Me) is detected through U-Net architecture as shown in Step 3 of the Figure 3. Input image resolution is RxK, and the LSTM cell is composed of 512 hidden units.
