Because noise is an important factor of image processing which degrade the original image quality and affect the appearance of images by hiding the important details of an image. So it is very important to detect the type ...
Nonlinear Noise ModelBeam Hardening EffectImage Processing Filters EffectThis paper proposes a more inclusive statistical model for predicting image noise in Computed Tomography (CT), associated with scanning factors, considering the effect of beam hardening and image processing filters. It is based on ...
模型输入两帧固定场景的噪声image pair,模型联合两个网络训练(denoiser and noise model),其一,对两帧图像建立noise2noise loss,训练denoiser网络;其二,基于残差得到noise,使用noise model loss去监督两者的噪声模型差异最小化(两者为固定场景base的噪声)。 noise2noise loss 在实际应用中,我们发现将Noise2Noise目标函数...
First, the structure of an image window is learnt adaptively by using a spatial general autoregressive (SGAR) model that is a uniform expression for both linear and non-linear autoregressive (AR) models. Parameters of the SGAR model are estimated in a moving window in the input low-...

Nd2 and the slope, kN , are the key parameters for the image sensor noise model in the ISP/Camera Simulator program, Simatest. Nd2 can be estimated from measurements of the minimum signal amplitude (digital number), minimum patch digital number, or noise amplitude VN as a function of DN...
Mechanisms for noise coupling in CMOS imagers are complex, since unlike a CCD, a CMOS imager has to be considered as a full digital-system-on-a-chip, with a highly sensitive front-end. In this paper, we analyze the noise sources in a photodiode CMOS imager, and model their propagation ...
