Image description based on exponent moments

The circular harmonic Fourier moments established on the basis of exponent,i.e.exponent moments(EMs)are demonstrated in this paper.The analysis of its principle and its relation with the CFMs verifies the multi distorted invariance that EMs as the orthogonal invariant moments possess.Through a series of simulation experiments on Matlab platform,the rotation invariance and position invariance of EMs were proved.A conclusion that the EMs are more suitable for image description and recognition than other moments since it is a highly concentrated image characteristic which has good sampling performance and strong anti noise ability,but has no information redundancy.
