英文摘要：

Zernike is a kind of region-based shape descriptor. This paper briefly introduces the concept of the Zernike moments and then discusses the improvement of the computation process of the Zernike moments. With an analysis of the merits of the Zernike moments, it suggests that the image can be reconstructed based on the invariant Zernike moments. The experiment of reconstructing image based on the improved invariant Zernike moments has proven the feasibility of the approach.
