Algorithm 1

Angle estimation based on PCA.
Input: the star image (x, y)
(1)Compute the bispectrum transformation of (x, y),
(2)Apply Gauss high pass filtering on , and obtain
(3)Perform threshold segmentation on , and obtain the position matrix of bright region pixels P
(4)Compute the mean of P, µ
(5)Compute the covariance matrix C
(6)Compute the maximum eigenvalue , and its eigenvector
(7)
Output:
