In this research, a matrix notation method to extract discrete orthogonal Racah moments is proposed to reduce the computation time. To verify this new computational method, the image reconstructions from higher orders of Racah moments are performed. Our experimental results show that the Racah moments computing time has been reduced tremendously, while the testing image can be reconstructed completely...
With the development of the moment technology, the moment descriptors have been used in many applications in the field of object recognition. In recent years, discrete orthogonal moments have been studied and proposed in moment applications as features to characterize image shapes. In this paper, a set of Racah moment based feature vectors is proposed for a Chinese character recognition system. The...
