THE MANAGEMENT AND REDUCTION OF DIGITAL NOISE IN VIDEO IMAGE PROCESSING BY USING TRANSMISSION BASED NOISE ELIMINATION SCHEME

open access: yesICTACT Journal on Image and Video Processing, 2022
Digital noise is an image defect that is approximately close to the pixel size and differs in brightness or color from the original image. Noise reduction plays an important role in the transmission, processing and compression of video footage and images.

Image Quality for Near-Eye Display Based on Holographic Waveguides

open access: yesApplied Sciences, 2022
The paper analyzes the image quality in augmented reality display based on holographic waveguides. Brightness, brightness non-uniformity, image noise, etc., depend on the parameters of the waveguide substrate, the configuration, and the relief shape of ...

Intrinsic Brightness Temperatures of AGN Jets [PDF]

open access: yes, 2006
We present a new method for studying the intrinsic brightness temperatures of the parsec-scale jet cores of Active Galactic Nuclei (AGN). Our method uses observed superluminal motions and observed brightness temperatures for a large sample of AGN to ...

Evidence for a Non-Expanding Universe: Surface Brightness Data From HUDF [PDF]

open access: yes, 2005
Surface brightness data can distinguish between a Friedman-Robertson-Walker expanding universe and a non-expanding universe. For surface brightness measured in AB magnitudes per angular area, all FRW models, regardless of cosmological parameters, predict

A Bright IDEA

open access: yesMolecular Systems Biology, 2020
Transcription factors (TFs) control the rate of mRNA production. Technological advances have made the task of measuring mRNA levels for all genes straightforward, but identifying causal relationships between TFs and their target genes remains an unsolved problem in biology.

Brightness of Synchrotron radiation from Undulators and Bending Magnets [PDF]

open access: yes, 2014
We consider the maximum of the Wigner distribution (WD) of synchrotron radiation (SR) fields as a possible definition of SR source brightness. Such figure of merit was originally introduced in the SR community by Kim.
