Decoding of the neural representation of the visual RGB color model. [PDF]
PeerJ Comput Sci, 2023 RGB color is a basic visual feature. Here we use machine learning and visual evoked potential (VEP) of electroencephalogram (EEG) data to investigate the decoding features of the time courses and space location that extract it, and whether they depend on a common brain cortex channel. We show that RGB color information can be decoded from EEG data and,

Modeling Dynamics of Leaf Color Based on RGB Value in Rice
Journal of Integrative Agriculture, 2014 This paper was to develop a model for simulating the leaf color changes in rice (Oryza sativa L.) based on RGB (red, green, and blue) values. Based on rice experiment data with different cultivars and nitrogen (N) rates, the time-course RGB values of ...

Peanut Leaf Wilting Estimation From RGB Color Indices and Logistic Models [PDF]
Frontiers in Plant Science, 2021 Peanut (Arachis hypogaea L.) is an important crop for United States agriculture and worldwide. Low soil moisture is a major constraint for production in all peanut growing regions with negative effects on yield quantity and quality. Leaf wilting is a visual symptom of low moisture stress used in breeding to improve stress tolerance, but visual rating ...
