Achromatic perception in color image displays [PDF]
, 1992 The perception of achromatic colors is an important aspect of CRT color appearance. Achromatic colors are important for practical reasons such as image color balance and as fundamental components of chromatic adaptation and color constancy research. Data

Paidéia (Ribeirão Preto), 2004 Surface color similarity may cause the perceptual grouping of uniform achromatic surfaces on an achromatic background both when the background is homogeneous and when the background contains achromatic context surfaces.

Integrative Zoology, EarlyView.Integrating comparative spectrometry, image analysis, and thermal modeling, we reveal that (1) females optimize crypsis via background matching, (2) males prioritize high‐contrast disruptive patterning at a significant thermoregulatory cost (reduced solar heat gain), and (3) habitat‐specific monomorphism in Diploderma slowinskii underscores ecological ...

Achromatic numbers and graph operations
, 2009 In this paper we investigate the achromatic number of the disjoint union of graphs and the achromatic number of the categorical product of graphs. We obtain the best possible upper and lower bounds for the union of graphs and the best possible lower ...

The oscillatory response of the electroretinogram and neuronal adaptation
Acta Ophthalmologica, EarlyView.Abstract After more than 50 years, there still remains a challenge and an interest to know more as well as extend and deepen our understanding of the small rapid wavelets, the oscillatory potentials (OPs), of the electroretinogram (ERG) and the neuronal adaptation of the retina.

Journal of Microscopy, EarlyView.Abstract Reproducibility challenges in bioimage analysis are common. The proliferation of tools and workflows creates a complex ecosystem that is difficult to reproduce without deliberate, explicit reporting and support. We assess the reproducibility of Gehrels et al.(2023) as a representative bioimage analysis workflow.

Traffic, Volume 27, Issue 3, September 2026.Variable‐angle total internal reflection fluorescence structured illumination microscopy (vaTIRF‐SIM) links nanoscale lateral organization with axial progression during clathrin‐mediated endocytosis. Super‐resolved TIRF‐SIM images resolve the lateral architecture of AP2‐labeled clathrin coats, while corresponding Z‐index maps report relative axial ...

Optical design of multilayer achromatic waveplate by simulated annealing algorithm
, 2008 We applied a Monte Carlo method - simulated annealing algorithm - to carry out the design of multilayer achromatic waveplate. We present solutions for three-, six- and ten-layer achromatic waveplates.

Dispensing Volumetric Additive Manufacturing
Advanced Functional Materials, Volume 36, Issue 44, 1 June 2026.Dispensing volumetric additive manufacturing (DVAM) prints 3D structures inside a photocurable resin droplet suspended from the tip of a glass pipette, enabling sequential printing without resin vats or manual part removal. Real‐time droplet profiling and ray‐tracing‐based correction compensate for optical distortion at the curved resin‐air interface ...

Neighborhood-Restricted [≤2]-Achromatic Colorings
, 2016 A (closed) neighborhood-restricted [≤2]-coloring of a graph G is an assignment of colors to the vertices of G such that no more than two colors are assigned in any closed neighborhood, that is, for every vertex v in G, the vertex v and its neighbors are ...
