Shape Prediction of Nasal Bones by Digital 2D-Photogrammetry of the Nose Based on Convolution and Back-Propagation Neural Network

Figure 4

Distances are practically measured for the nasal bones, in which horizontal , , and are the width of nasal bones at the nasomaxillary suture line, nasion, and nasofrontal suture, perspectively. With red line, it illustrated the distance between nason and sellion (dimensions are shown in mm) (a). Nasal bone had been removed, ligament and soft tissue captured from the right side (b).
