A Bright IDEA [PDF]

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.

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 ...

SVPA - THE SEGMENTATION BASED VISUAL PROCESSING ALGORITHM (SVPA) FOR ILLUSTRATION ENHANCEMENTS IN DIGITAL VIDEO PROCESSING (DVP)

open access: yesICTACT Journal on Image and Video Processing, 2022
At the present time photographic visual processing is rapidly moving towards the next stage. In addition, a variety of visual processing technologies are evolving, such as splitting image dimensions, calibration, pixel beautification, and high-resolution

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.

Data‐driven performance metrics for neural network learning

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView., 2023
Summary Effectiveness of data‐driven neural learning in terms of both local mimima trapping and convergence rate is addressed. Such issues are investigated in a case study involving the training of one‐hidden‐layer feedforward neural networks with the extended Kalman filter, which reduces the search for the optimal network parameters to a state ...

Investigation of the Uniformity of Gel Shrinkage by Imaging Tracer Particles Using X‐Ray Microtomography

open access: yesAdvanced Engineering Materials, EarlyView., 2023
A novel method for tracking structural changes in gels using widely accessible microcomputed tomography is presented and validated for various hydro‐, alco‐, and aerogels. The core idea of the method is to track positions of micrometer‐sized tracer particles entrapped in the gel and relate them to the density of the gel network.

Error Analysis of Atmospheric Visibility Measurements Based on an Image Brightness Contrast Method

open access: yesIEEE Access, 2020
The method of image visibility detection is one of the methods closest to human vision. It is based on the principle of human eye observation but avoids the errors resulting from human subjectivity.

A Morphological-type dependence in the mu_0-log(h) plane of Spiral galaxy disks [PDF]

open access: yes, 2001
We present observational evidence for a galaxy `Type' dependence to the location of a spiral galaxy's disk parameters in the mu_0-log(h) (central disk surface-brightness - disk scale-length) plane.
