Abstract: (8607 Views)
The quality of the image formed by an optical system is reduced by aberrations. This paper points out and attempts to correct blindness of lens aberration. Therefore modified Zernike moments were introduced to present lens aberration model within which their coefficients were estimated through poly-spectral analysis. The model parameters are divided into asymmetric and symmetric which are estimated through bi-coherence and tri-coherence respectively. The obtained precision compares favorably to the aberration given by state of the art ploy-spectral analysis and reaches a RMSE of 0.1 pixels.
