... measurement matrix has a maximum rank of two. The matrix P contains the pose or orientation for each trajectory. The matrix S contains the shape of the nominal trajectory for this activity. Using the ... The error matrix is calculated as the difference between the tested trajectory matrix T x and the rotated activity shape as follows: Δ x = T x −s x R x S. (23) The Frobenius norm o...
