Abstract

Coffee is a traditional drink in India after tea. The demand for coffee is increasing day by day among youngsters. There are different types of beverages made in coffee as per its aroma & color, and it depends on the roasting levels of coffee beans. Most specialty coffees have been sorted and processed by hand. The coffee roasting degree is mainly based on the coloring of beans and is directly related to the beverage quality. There are four levels of roasting: green, light roast, medium roast, and dark roast. This manuscript proposed a convolutional neural network to classify the four- roasting level of coffee beans and achieved 97.5% accuracy.
