A target digital image is received from an image sensor. The image is contaminated by noise of unknown magnitude that is represented by a reference digital image. A process is applied that uses statistical analysis of the target digital image and of the reference digital image to estimate a mag...
A method of processing a digital image, include the steps of: specifying a noise control parameter; employing the noise control parameter to process the digital image to reduce the noise in the digital image; and employing the noise control parameter to process the digital image to adjust the ...
Consequently, this approach has an obvious advantage when used in real-time digital image processing applications and where a parallel processor can be used. For both the additive and multiplicative cases, the a priori mean and variance of each pixel is derived from its local mean and variance....
In digital images, x stands for the gray-level, so it is non-negative and often defined as integer x∈[0,255]. Figure 7(a) shows a raw brain image extracted from Open Access Series of Imaging Studies (OASIS) brain dataset [73]. Figure 7(b-c) present the Gaussian noise injection ...

Digital holography (DH) has emerged as one of the most effective coherent imaging technologies. The technological developments of digital sensors and optical elements have made DH the primary approach in several research fields, from quantitative phase i
Digital image processing is a part of digital signal processing. Digital image processing has many significant advantages over analog image processing. Image processing allows a much wider range of algorithms to be applied to the input data and can avoid problems such as the build-up of noise ...
In the context of digital photography, noise is aberrant pixels that appear in your image files. In other words, noise is made up of pixels not correctly representing the color or exposure of the scene. If you photograph a dark blue wall, and in certain portions of the file, you can see...
