Image-Based Classification of Robusta Coffee Roasting Degree Using LDA–KNN with Color and Shape Features

Oleh: Ritonga, Desi Kris Tanti, Ahmad, Usman, Mardjan, Sutrisno Suro

The determination of robusta coffee roast levels is commonly conducted through visual assessment, which is inherently subjective and prone to inconsistency due to overlapping visual characteristics between adjacent roasting stages. On the other side, objective measurement equipment is often costly a...
