The photon shot noise is a noise of the signal dependency where the photon is generated by fluctuation when the photon hit the receiving optical part of the image sensor.
We have a median filter and a average filter as conventional methods of noise reduction. when you use these linear filters the edge part of a original signal is attenuated at the same time as removing the noise. The weiner filter is a method comparatively effective to the edge preservation. However, the weiner filter is an effective filter only in case of the gaussian noise. There is a problem that it is not possible to adjust because the photon shot noise is distributed a poisson noise. In this paper we uses M-transform that is the signal transformation based on M-sequence signal. M-transform converts the noise into an irregular signal of a small amplitude. And the image is restored by using ε filter. As a result, The noise reduction was suggested. |
