An Invariant Region-Shape Descriptor Based on Fourier Transform

WANG Bin 1,2(1.Key Laboratory of Electronic Business,Nanjing University of Finance and Economics,Nanjing,Jiangsu 210046,China;2.School of Biomedical Engineering,Southeast University,Nanjing,Jiangsu 210096,China)  
A novel invariant region-shape descriptor based on Fourier transform is proposed in this paper.In this method,a shape pixel-matrix is firstly generated by image re-sampling using polar raster.Two times of 1D Fourier transforms and a correcting operator of phase are then conducted against the shape pixel matrix.The resulting matrix formed by the Fourier coefficients of low frequency is used to describe the region shape.The obtained shape descriptor not only preserves the phase information of the Fourier coefficients,but also achieves invariance to translation,scale and rotation.The experimental results show that the proposed method outperforms the existing Fourier region-shape descriptor and Zernike moment descriptor.
