Optimizing the color-to-grayscale conversion for image classification

Signal, Image and Video Processing, 2015
In many of the computer vision applications, color-to-grayscale conversion algorithms are required to preserve the salient features of the color images, such as brightness, contrast and structure of the color image. The traditional color-to-grayscale conversion algorithms such as National Television Standards Committee (NTSC) may produce mediocre ...

GCIPL color coding on OCT predicts glaucoma conversion in normal-tension glaucoma suspects, including a high myopia subgroup [PDF]

Scientific Reports
This retrospective study investigated the predictive value of OCT-derived color coding in assessing the risk of glaucoma conversion among normal-tension glaucoma (NTG) suspects, with a particular focus on highly myopic eyes. A total of 307 eyes underwent

Multispectral Image Generation from RGB Based on WSL Color Representation: Wavelength, Saturation, and Lightness

Computers, 2023
Image processing techniques are based nearly exclusively on RGB (red–green–blue) representation, which is significantly influenced by technological issues. The RGB triplet represents a mixture of the wavelength, saturation, and lightness values of light.

Investigation of Quantum Dot Color Filter Micro-LED Display

Photonic Sensors, 2023
In this work, we present the investigation of the quantum dot color filter (QDCF) micro-light emitting diode (micro-LED) display. Green and red quantum dot photoresist (QDPR) materials are patterned into a pixelated array and precisely bonded with an all-

Alleviating the crosstalk effect via a fine-moulded light-blocking matrix for colour-converted micro-LED display with a 122% NTSC gamut

Light: Advanced Manufacturing, 2022
One of the major challenges when fabricating high gamut colour-converted micro-light-emitting diodes (LEDs) displays is severe crosstalk effect among adjacent pixels because of the wide view-angle feature of micro-LED chips.
