====== MTFCorrection ======
Use this module to enhance the image amplitudes of input 2D or 3D images to correct for the modulation transfer function ("MTF") of the detector used during image acquisition.

===== Parameters and I/O =====

|< 100% 30% >|
^ Parameters                 ^ Description     ^
| Fill filter with zeros  | When checked, the 2D filter function in the corners will be set to zero. |
| MTF data - //Internal//  | Use supplied MTF functions. |
| -> MTF data from   | Specify which supplied MTF function to use |
| MTF data - //External//  | Use custom MTF function, which has to be supplied as input. |

|< 100% 30% >|
^ Input   ^ Description ^
| Micrographs  | Stack of 2D or 3D images to be corrected for the MTF. |
| //MTF//  | two dimensional MTF data of the detector used to record the data. |

| 1d rot avg of power spec of output | One dimensional rotational average of the power spectrum of the corrected output images. |
| 1d rot avg of power spec of input | One dimensional rotational average of the power spectrum of the input images. |
| Corrected | MTF corrected stack of images. |
| Enhancement curve | Factors used to scale the spatial frequencies of the input data.. |
