An Improved Algorithm of Pseudo-Zernike Moments
Hanqiang Cao · Computer Technology and Development · 2007
Pseudo-Zernike moments are widely used in the fields of pattern recognition due to their properties such as orthogonality,rotation invariance.But for the complexity of Pseudo-Zernike moments,the problem of computation of Pseudo-Zernike moments has not been well solved yet.In this paper,present an improved algorithm based on mapping rectangular image into a unit circle and apply it to the recognition of Arabic numerals.The experimental results show that the improved algorithm has better performance in both calculation time and recognition precision.
