Javaid A. Sheikh, in Healthcare Data Analytics and Management, 2019 4.2.2 Additive white Gaussian noise To evaluate fragility, the image is tested with additive white Gaussian noise (AWGN). The resulting images and objective metrics are shown in Fig. 11 and Table 8, respectively. Sign in ...

We present a simple and usable noise model for the raw-data of digital imaging sensors. This signal-dependent noise model, which gives the pointwise standard-deviation of the noise as a function of the expectation of the pixel raw-data output, is composed of a Poissonian part, modeling the...
A new approach to estimation of Gaussian noise in digital images is presented. As a first step, a nonlinear amplification of the noise is provided by adopting a multiparameter piecewise linear (PWL) sharpener. Thus, the noise is estimated by analyzing the edge gradients of the data filtered by...
Here, the method first takes an input image which is a colour image and preprocessing of image is done to denoise. Preprocessing is one of the important processes in de-noising, it involves the following process removing lowfrequency background noise, normalizing the intensity of the individual ...
I'm unsure of what you mean by noise percentage but it shouldn't be changing based on the image size. If by percentage you mean how much more noise on each pixel, then you should increase the variance. If you mean the amount of pixels that have noise added to them, then you can ma...
Accurate characterization of the noise influencing a quantum system of interest has far-reaching implications across quantum science, ranging from microscopic modeling of decoherence dynamics to noise-optimized quantum control. While the assumption that
