# PseudoInverse

Image restoration filter

## SYNOPSIS

`#include "dip_restoration.h"`

dip_Error dip_PseudoInverse ( in, psf, out, threshold, flags )

## FUNCTION

This function performs a basic, very noise sensitive image restoration operation by inverse filtering the image with a clipped point spread function. Each frequency in the output for which the response of the PSF is smaller than `threshold` is set to zero.

## ARGUMENTS

`dip_Image` | `in` | Input image
`dip_Image` | `psf` | Point spread function image
`dip_Image` | `out` | Output image
`dip_float` | `threshold` | Threshold value
`dipf_Restoration` | `flags` | Restoration flags
