Gij and Oij are the achieve coefficient and bias coefficient received after two-issue correction respectively, and the expressions of bias coefficient Gij and achieve coefficient Oij are proven in Equation (five). The wavelet coefficients are nonlinearly transformed by noise estimation to suppress large-frequency noise and retain details.
