摘要

一般的数字图像，尤其是x光照片，主要受到光子计数噪声的影响。在本文中，我们提供了一种估计成像传感器增益和与每个图像灰度级相关的光子计数噪声方差的方法。这对多个范围都很有用，比如逆向工程和去噪。

A new and reliable Poisson noise estimator for radiographic images

Digital images in general, and radiographies in particular, are mainly affected by photon counting noise. In this paper, we provide a method to estimate the gain of the imaging sensor and the variance of the photon counting noise associated to each image grey level. This is useful to multiple scopes, like reverse engineering and denoising.
