Image quality reduces because of the image acquisition or transmission [7]. Before applying further processing on the image, noise should remove from the image. In this paper, various technologies as well as their filters to detect and remove the noise are discussed.Gursharan Kaur...
Imatest has a powerful Image Sensor Noise model, derived from measurements of raw images, which can be used in the Simatest Camera/Image Signal Processing Simulator to predict camera performance under a wide variety of conditions. Noise scales strongly with pixel size. It can be very low in hi...
The mean and variance parameters for "gaussian", "localvar", and "speckle" noise types are always specified as if the image were of class double in the range [0, 1]. If the input image is a different class, the imnoise function converts the image to double, adds noise according to ...

An image processing apparatus comprising: an inputting unit configured to input a plurality of pieces of image data; an aligning unit configured to perform aligning processing of a plurality of images represented by the inputted image data; an average image generating unit configured to generate...
Notably, we named these types of feedback emotionally incongruent feedback and emotionally congruent feedback. We hypothesized that incongruency between the valence of the emotional face and the valence of the feedback could induce perceptual uncertainty regarding the feedback, which we named social ...
Other types of noise Thermal noise can be described as Gaussian white noise. Noise in semiconductor devices approximates to a Gaussian white characteristic over a limited range. Active devices such as transistors and opamps depart from this at both ends of the spectrum. At low frequencies, the ...
confirmed by COMSOL simulations for the platform shown in Fig.1e. Below, we distinguish between two types of noise that might affect the performance of a sensor9: (a) multiplicative noise associated with classical noise sources describing a noisy NR-EPD, and (b) additive noise associated with...

20,21,22,23,24,25,26 considered different types of optimization problems and explored adding different types of noise and its amount to different types of search procedures to find an optimum. They include adding noise to extricate a search from a saddle point or improve local searches to ...
As demonstrated through our field testing, the heterodyne synthesizer, which generates low phase noise signals directly at high carrier frequencies, opens up a new technology space for these types of systems. As a result, it may enable higher resolution and sensitivity for future air- and ...
