Abstract

RUGE RUGE, Ilber Adonayt; PINZON ARIAS, Arthur Steven  and  MORENO OCHOA, Daniel Enrique. An automatic sorting system based on coffee-grain color identification for the "excelso" presentation using image processing. Tecnura [online]. 2012, vol.16, n.34, pp.84-93. ISSN 0123-921X.

This paper describes an application of digital-image processing using multi-threshold techniques intended to solve an existing problem at the low- and medium-production coffee farms. The motivation behind this study is that these farms do not have a suitable procedure (in terms of production and cost) to perform coffee selection ("excelso" coffee) automatically and have to resort to selecting this product manually.

Keywords : Excelso coffee; digital image processing; screening; multilevel threshold..
