It has been known that short-time auditory stimulation can contribute to the improvement of the balancing ability of the human body. The present study aims to explore the effects of white Gaussian noise (WGN) of different intensities and frequencies on d
4.1 Gaussian Noise Figure 4 illustrates an example of removing additive white Gaussian noise via wavelet shrinkage. Figure 4(a) and Fig. 4(b) display the original “Barbara” image and a noisy version, respectively. The PSNR of the noisy image is 24.6 dB. Figure 4(c) and Fig. 4(d) ...
An example of zero-mean white Gaussian noise with a variance of σn2 = 0.25 is shown in Figure 3.3(b). Even if this assumption may not hold in certain cases, it does help make the mathematical analysis of digital communication systems tractable. The receiver has to make a decision on ...
Our method (Ours) then estimates those parameters based on the noisy and noise-free image pair using the cumulant expansion. As a baseline we implement another estimator based on variance (Var) which also uses such image pairs. For the above example, we get the estimates and the log-...

Disclosed are methods, devices, and computer program products for image noise reduction. In one example embodiment, a method for reducing noise in a digital image includes several acts. First, one or more objects are identified in an input image. Next, the input image or a portion thereof is...
The application of image processing in industry has shown remarkable success over the last decade, for example, in security and telecommunication systems. The denoising of natural image corrupted by Gaussian noise is a classical problem in image processing. So, image denoising is an indispensable step...

In the literature two main groups of methods for Mixed Gaussian and Impulsive Noise (MGIN) removal are proposed. The straightforward methods of enhancing the noisy image first remove the impulses and then, in the second step, an appropriate filter, designed to reduce the Gaussian noise, is used...
