Function Documentation

Gan_Bool gan_fundamental_matrix_fit (  Gan_Vector3 *    p1, Gan_Vector3 *    p2, int    n, Gan_SymMatEigenStruct *    sme, Gan_Matrix33 *    F )

Computes the fundamental matrix from point matches. Parameters: p1  The array of image points in image 1 p2  The array of image points in image 2 n  The number of point matches sme  An eigensystem structure to use or NULL F  The fundamental matrix to be filled Applies the Longuet-Higgins eight-point algorithm to compute the fundamental matrix for images 1 & 2. If the #sme structure to compute eigenvectors & eigenvalues is passed as NULL, a suitable structure is allocated and freed inside the function. Returns: GAN_TRUE on success, GAN_FALSE on failure. Warning: The rank-2 constraint on is not imposed. Any normalisation of the image data should be applied before using the function. See also: gan_essential_matrix_fit().
