Inthis study, we present a new method for the noise reduction of images contaminated withGaussian noise by using fuzzy image filter with the help of fuzzy rules which make useof membership functions. In this article, fuzzy derivative concept is also applied toperform fuzzy smoothing. This method...
TheGaussian filteris a spatial filter that works by convolving the input image with a kernel. This process performs a weighted average of the current pixel’s neighborhoods in a way that distant pixels receive lower weight than these at the center. The result of such low-pass filter is a b...

To alleviate the above-mentioned problems, numerous image restoration approaches were designed to first remove impulsive noise and then, to apply an efficient filter intended for the reduction of the Gaussian noise component26,27,28,29,30. The rationale behind such an approach is that the nature ...

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...
Image denoisingPDE modelA Gaussian noise reduction technique for grayscale images is proposed in this article. It uses a modified Gaussian filter kernel based on a hyperbolic second-order equation. The introduced mathematical model differs from the classic Gaussian model provided by the heat equations...
settings or in low lighting conditions. In this case, Gaussian blur is a noise-reduction image processing/image filtering technique that will "smooth out" the noise pixels (by smoothing uneven pixel values) and make it less obvious that the original image was taken in not-so-ideal ...
3.2.1 Adaptive Gaussian filter Gaussian filtering is a linear smoothing filter that eliminates Gaussian noise and is widely used in the noise reduction process of image processing. In general, Gaussian filtering is a process of weighted averaging of the entire image. The value of each pixel is ...
