Measure for Recognition($\kappa$):

Four affine homography related views of an aircraft are shown in figure 1. The $\Theta$ matrix for these four views was formed using the measures of $\kappa$ for each view as described earlier. The rank of this matrix $\Theta$ was found to be 1 using SVD (the number of non-zero singular values gives the rank of the matrix) , as the largest four singular values were 51138.4, 0.0056, 0.0028, and 0.0026.
