Multiresolution wavelet moments, relating wavelet analysis with theory of moment invariants, are perfect representations of moments in multiresolution wavelet transform. Wavelet moments calculated by approximation components at certain scale level correspond to the visual invariants at multiresolution wavelet spaces.

Multiresolution wavelet moments, relating wavelet analysis with theory of moment invariants, are perfect representations of moments in multiresolution wavelet transform. Wavelet moments calculated by approximation components at certain scale level correspond to the visual invariants at multiresolution wavelet spaces. But because of its computation complexity, it is difficult to be implemented in real time. A fast projection-based algorithm for two-dimensional wavelet moments is presented. In the approach, the computation of a two-dimensional wavelet transform moment can be performed in several one-dimensional spaces, thus reducing the computational complexity without introducing extra error.

License plate character recognition is a main step in license plate recognition system, but its emphasis is to choose efficient features. Wavelet motion is a new visual invariant, it is a integration of moment and wavelet multi-scale analysis. Wavelet moment feature of image can reflect the image's part and whole characters and has strong anti-jamming ability. But different method of discretization of wavelet moment shows different performance. On the basis of analysis of wavelet moment, the paper introduces the algorithm of discretization of wavelet moment, and applies it to license plate character recognition system. With the wavelet moment features and improved BP neural network, the recognition of license plate character is realized and good performance gained.
