Redefining A in RGBA: Towards a Standard for Graphical 3D Printing [PDF]

open access: yes, 2019
Advances in multimaterial 3D printing have the potential to reproduce various visual appearance attributes of an object in addition to its shape. Since many existing 3D file formats encode color and translucency by RGBA textures mapped to 3D shapes, RGBA

A CIELAB Color Classification Scheme for Poinsettias [PDF]

open access: yesHortScience, 1997
Forty-two poinsettia cultivars were grown as a 15-cm single-plant pinched crop at 21/16.5°C (day/night) temperatures during Fall 1995 with standard commercial practices for irrigating, fertilizing, and pest control. On 7 Dec., 156 consumers rated the cultivars for their overall appeal.

The alternating least squares technique for nonuniform intensity color correction [PDF]

open access: yes, 2014
Color correction involves mapping device RGBs to display counterparts or to corresponding XYZs. A popular methodology is to take an image of a color chart and then solve for the best 3 × 3 matrix that maps the RGBs to the corresponding known XYZs ...

High Light Utilization and Color Rendering in Vacuum‐Deposited Semitransparent Perovskite Solar Cells

open access: yesAdvanced Materials, EarlyView.
In this work, low bandgap (≈1.55 eV) semitransparent perovskite solar cells (ST‐PSCs) having thin (thickness < ≈100 nm) perovskite layers and transparent conductive oxide‐based rear electrodes are fabricated using vacuum‐deposition methods. Two different ST‐PSCs demonstrated a high light utilization efficiency value of 4.2 (PCE: 9.26% and AVT: 45.3 ...

Clinical Validation of Imaging Biomarkers in Mycosis Fungoides. [PDF]

open access: yesExp Dermatol
ABSTRACT The composite index lesion severity (CAILS) score is used to monitor disease and therapeutic response in mycosis fungoides (MF), but is limited by interobserver variability and low sensitivity. Emerging imaging techniques, such as multispectral imaging (MSI), colourimetry and laser speckle contrast imaging (LSCI), offer objective alternatives ...

Transparent Perovskite Light‐Emitting Diodes with Conductive Oxide Top Electrodes

open access: yesAdvanced Materials, EarlyView.
Transparent perovskite light‐emitting diodes (TrPeLEDs) enable simultaneous display and transparency, expanding application possibilities. Using a metal oxide buffer layer and pulsed laser deposition, TrPeLEDs with diverse compositions and architectures are demonstrated.

Intelligent Stain‐Free Histology on Structural Colorimetric Nanocavities

open access: yesAdvanced Science, EarlyView.
Chen and Gan et al. introduce a label‐free imaging platform using inexpensive Nanocavity‐on‐Silicon (NOS) slides. These slides transform subtle tissue variations into vivid structural colors, enabling high‐contrast histological imaging under a regular optical microscope. This stain‐free approach reveals morphological details comparable to traditional H&

Vigour testing for the rice seed with computer vision-based techniques

open access: yesFrontiers in Plant Science, 2023
Rice is the staple food for approximately half of the world’s population. Seed vigour has a crucial impact on the yield, which can be evaluated by germination rate, vigor index and etc.

Automated Discovery of Multicellular Behavior for Optimized Plant Growth and Climate Resilience

open access: yesAdvanced Intelligent Systems, EarlyView.
An automated robotic system is described for rapid scientific experimentation with multicellular organisms. By enhancing a robotic liquid handler with a custom developed deep learning algorithm and camera module, samples and data are prepared with minimal human intervention.

Non-noticeable information embedding in color images: marking and detection [PDF]

open access: yes, 1999
One of the problems arising from the use of digital media is the ease of obtaining identical copies of digital images or audio files, allowing manipulation and unauthorized use. Copyright is an effective tool for preserving intellectual property of those
