Retina‐Inspired Color‐Cognitive Learning via Chromatically Controllable Mixed Quantum Dot Synaptic Transistor Arrays

Advances in Materials, 2022
Artificial photonic synapses are emerging as a promising implementation to emulate the human visual cognitive system by consolidating a series of processes for sensing and memorizing visual information into one system.

Deep and Low-Rank Quaternion Priors for Color Image Processing

IEEE transactions on circuits and systems for video technology (Print), 2023
Due to the physical nature of color images, color image processing such as denoising and inpainting has shown extensive and versatile possibilities over grayscale image processing.

Monochromatic Partitions In Local Edge Colorings

Acta Mathematica Hungarica, 2020
An edge coloring of a graph is called a local \(r\)-coloring if the edges incident to any vertex are colored with at most \(r\) distinct colors. The two main results established in this paper are as follows.\par (1) Let \(r \geq 1\) and \(n \geq r^{2(r+2)}\) be integers.

Color object identification by monochromatic binary correlation

Applied Optics, 1988
A real-time polychromatic image correlator that uses a magnetooptic (MO) spatial light modulator (SLM) device for pattern recognition based on both the color and shape of an input object is presented. The proposed system utilizes a multichannel spectral matched spatial filter employed in a binary coherent optical correlator.

Narrow-Band Red-Emitting Phosphors with High Color Purity, Trifling Thermal and Concentration Quenching for Hybrid White LEDs and Li3Y3BaSr(MoO4)8:Sm3+, Eu3+-Based Deep-Red LEDs for Plant Growth Applications.

Inorganic Chemistry, 2022
Trivalent europium-based monochromatic red light-emitting phosphors are an essential component to realize high-performance smart lighting devices; however, the concentration and thermal quenching restrict their usage.

Low-Rank Quaternion Approximation for Color Image Processing

IEEE Transactions on Image Processing, 2020
Low-rank matrix approximation (LRMA)-based methods have made a great success for grayscale image processing. When handling color images, LRMA either restores each color channel independently using the monochromatic model or processes the concatenation of

Coloring Ordered Sets to Avoid Monochromatic Maximal Chains

Canadian Journal of Mathematics, 1991
AbstractThis paper is devoted to settling the following problem on (infinite, partially) ordered sets: Is there always a partition (2-coloring) of an ordered set X so that all nontrivial maximal chains of X meet both classes (receive both colors)?

Special monochromatic trees in two-colored complete graphs

Journal of Graph Theory, 1997
Let \(G\) be a graph. A set \(S\) of \(k+ 1\) vertices of \(G\) form a \(k\)-cluster in \(G\) if the difference between the degrees of any two vertices in \(S\) is at most \(k-1\). Given a graph \(H\), let \(R_k(H)\) be the minimum of positive integers \(n\) such that any graph \(G\) with at least \(n\) vertices has the property that either \(G\) or ...
