Camera color vision for crop ripeness model.

Color is the main indicator used to recognize ripeness of the agricultural products and thus determine the best time to harvest the products. In this research, a Nikon coolpix 4500 digital camera (Nikon, Japan) was used to investigate the relationship between oil content in oil palm fruit and its su...
