Japan: Smartphone camera used to estimate vegetable taste
The application analyzes the images of the external appearances of agricultural products such as vegetables and fruits. It creates histograms of the three primary colors of visible light and estimates the taste of the targeted agricultural product based on the correlation between the histograms and taste data that has been quantified by using a taste sensor in advance. As a taste sensor, Makuta Amenity used a system developed by Intelligent Sensor Technology Inc, a venture firm that develops taste sensors.
In the same way, the application estimates the amounts of nutrients contained in an agricultural product. To increase estimation accuracy, it uses only taste and nutrient elements with which 80% or higher correlation has been confirmed.
The correlation between tastes (or nutrients) and image data is stored in a database developed by Makuta Amenity. And the application accesses the database via a network.
