ICTACT 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.

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

Achromatic Cues Are Important for Flower Visibility to Hawkmoths and Other Insects
Frontiers in Ecology and Evolution, 2022 Studies on animal colour vision typically focus on the chromatic aspect of colour, which is related to the spectral distribution, and disregard the achromatic aspect, which is related to the intensity (“brightness”) of a stimulus.

Dark-Bright Discrete Solitons: A Numerical Study of Existence, Stability and Dynamics [PDF]
Physica D 240 (2011) 767-778, 2010 In the present work, we numerically explore the existence and stability properties of different types of configurations of dark-bright solitons, dark-bright soliton pairs and pairs of dark-bright and dark solitons in discrete settings, starting from the anti-continuum limit. We find that while single discrete dark-bright solitons have similar stability

Frontiers in Human Neuroscience, 2014 Previous work demonstrated that perceived surface reflectance (lightness) can be modeled in simple contexts in a quantitatively exact way by assuming that the visual system first extracts information about local, directed steps in log luminance, then ...

Consecutive Bright Pulses in the Vela Pulsar [PDF]
2011, ApJ, 735, L17, 2011 We report on the discovery of consecutive bright radio pulses from the Vela pulsar, a new phenomenon that may lead to a greater understanding of the pulsar emission mechanism. This results from a total of 345 hr worth of observations of the Vela pulsar using the University of Tasmania's 26 m radio telescope to study the frequency and statistics of ...

Sowing depth and light intensity in the emergence and development of monocotyledonous weeds
Bioscience Journal, 2022 This study aimed to evaluate the effects of different sowing depths and light intensities on the emergence and development of the monocot weed species, Urochloa decumbens and Cenchrus echinatus, under field conditions.
