Abstract:Abstract:We present an efficient and reliable algorithm for determining the orientations of noisy images obtained from projections of a three-dimensional object. Based on the linear relationship among the common line vectors in one image plane, we construct a sparse matrix, and show that the coordinates of the common line vectors are the eigenvectors of the matrix with respect to the eigenvalue 1. The projection directions and in-plane rotation angles can be determined from these coordinates. A robust computat… Show more
