Sistema de selección electrónico de café excelso basado en el color mediante procesamiento de imágenes

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.
