Intelligent non-destructive classification of josapine pineapple maturity using artificial neural network

The pineapple maturity level also referred as pineapple maturity index is based on the percentage of yellowish that appears on the pineapple’s skin. In pineapple industry to determine the level of maturity, human experts adopt methods based on their subjective assessment of skin color. To this day,...
