AN Efficient Shape Extraction Method Using Main Contour Curve Approximation Based Fourier Descriptor

摘要

How to make image retrieval become more accurate and more humanity is a great challenge to all of us.In this paper,we propose new modified Fourier sharp descriptor algorithm.It originates from the old Fourier algorithm.Compared with the former algorithm,our method has better performance.Experiments results show that it is effective and with less need of storage space and computing time.
