Resumen o descripción
We present a detailed analysis of the reconstruction of graylevel
images using orthogonal moments with respect to the basis sets of
Zernike, Fourier-Mellin, Chebyshev-Fourier, and pseudo-Jacobi-Fourier
polynomials. As test images, we use Ronchigrams with different numbers
of fringes as high-spatial-frequency components. The evaluation of
image reconstruction between orthogonal moment sets is made in terms
of different metrics. These measurements are the normalized image reconstruction
error, the overall activity level in each image with respect to
spatial frequency variations, the root-mean-square contrast, the total
number of reconstructed fringes, the coordinate transformations of the
input image, and the number of moment orders. Moreover, a method of
denoising the input image based on the Daubechies wavelet transform is
implemented to compute the signal-to-noise ratio. Numerical computations
show that, for the Ronchigram reconstructions, the performance of
Zernike moments is better than that of the other basis sets of orthogonal
moments.
