Evaluation of the Effect of 1-MCP Treatment on Flesh and Surface Color of Selected European and Asian Plum Fruit Using Machine Vision

open access: yesHorticulturae, 2023
The aim of this work was to evaluate how 1-methylcyclopropene (1-MCP) treatment affects appearance of plum fruit. Fruit of ‘Angeleno’ and ‘Topend’ cultivars were treated with 625 ppb gaseous 1-MCP at 1 °C for 24 h after harvest. Samples without treatment,

Foraging Small White Butterflies, Pieris rapae, Search Flowers Using Color Vision

open access: yesFrontiers in Ecology and Evolution, 2021
We demonstrate that the small white butterfly, Pieris rapae, uses color vision when searching flowers for foraging. We first trained newly emerged butterflies in a series of indoor behavioral experiments to take sucrose solution on paper disks, colored ...

Assessing the color status and daylight chromaticity of road signs through machine learning approaches

open access: yesIATSS Research, 2023
The color of road signs is a critical aspect of road safety, as it helps drivers quickly and accurately identify and respond to these signs. Properly colored road signs improve visibility during the day and make it easier for drivers to make informed ...

Visual task identification and characterisation using polynomial models [PDF]

open access: yes, 2006
Developing robust and reliable control code for autonomous mobile robots is difficult, because the interaction between a physical robot and the environment is highly complex, subject to noise and variation, and therefore partly unpredictable.
