摘要
To deal with the large amount of computation of moments during matching, we propose a novel fast matching algorithm based on moment invariants. This algorithm utilizes the computational characteristic of moments and sets ten sum-tables to reduce the computational complexity of moments during matching. With the proposed algorithm, lower order moments of each sub-image can be determined by using only a few additive and multiplicative operations, which shortens the matching time greatly. Meanwhile, the proposed algorithm computes moment features directly from the gray value of image and the result is accurate and independent from the matching precision. Simulation results illustrate the effectiveness of the proposed algorithm.
