WebJun 1, 2011 · The (affine-invariant) length of each edge is defined by L 2 (dx, dy) = g 11 dx 2 + 2 g 12 dxdy + g 22 dy 2. Specifically, for our canonical triangle with vertices at (0,0), (1,0) and (0, 1) we have L 1 2 = g 11, L 2 2 = g 22 and L 3 2 = g 11 − 2 g 12 + g 22.Each edge may appear in more than one triangle.

"WebSeveral prior works have investigated the affine invariant features that are robust to slight pose variations or view changes. Nevertheless, the 2D model fails to represent large pose variations due to self-occlusion and the perspective distortion introduced when the face is close to cameras. " - Affine invariant
