A new method for human face image scale and direction estimation is proposed using covariance matrix eigenvalue and eigenvector of edge set, which is proved by theory and experiments.
For this special multisensor system, distributed optimal fusion algorithm is received by avoiding computing correlated estimationcovariance based on the matrix operation.
