Driving Waveform Design of Electrophoretic Display Based on Optimized Particle Activation for a Rapid Response Speed

open access: yesMicromachines, 2020
Electrophoretic displays (EPDs) have excellent paper-like display features, but their response speed is as long as hundreds of milliseconds. This is particularly important when optimizing the driving waveform for improving the response speed.

Characterization of the Relationship between the Loess Moisture and Image Grayscale Value

open access: yesSensors, 2021
This paper presents a model for estimating the moisture of loess from an image grayscale value. A series of well-controlled air-dry tests were performed on saturated Malan loess, and the moisture content of the loess sample during the desiccation process

Saliency Consistency-Based Image Re-Colorization for Color Blindness

open access: yesIEEE Access, 2020
For patients with color vision defects, owing to the destruction of cone cells and loss of function, some color information is lost, hence changing the originally transmitted information by the image.
