  noise correction
Noise correction for roughening analysis of magnetic flux profiles in YBa$_\mathsf{2}$Cu$_\mathsf{3}$O$_\mathsf{7-x}$
      
After noise correction, we find that the magnetic field profile is characterized by a roughness exponent $\alpha = 0.75(6)$.
      
This dark current also degrades the performance of cameras containing these pixels by increasing the residual fixed pattern noise following fixed pattern noise correction.
      
Although not exploited in this work, the features of the proposed model make it feasible for noise correction in 3-D PET.

In astronomical high resolution image reconstruction, Fourier modulus recovery is as important as the phase recovery of a object, because there are many kinds of complex noise in observations and the recovery of modulus or phase will become more difficult. To solve the problem of the noise of all kinds in the modulus recovery, some appropriate methods are provided. The experimental results of image reconstruction show that these methods are effective and necessary, they ensured the high precision modulus recovery....
