Abstract :
This chapter presents a strategy to identify coffee fruits in five different maturation stages. The strategy is based on the separation among color loci of coffee fruits in different maturation stages, in the RG plane. To take advantage of this separation, a calibration algorithm was developed to delimit the regions. The algorithm was complemented with expertspsila criteria to make decisions in the intersections. The calibration procedure produces an identification matrix that is then used to recognize the maturation stage of fruits passing in front of an optoelectronic device. The system showed acceptable efficacies with a simple sensor and an inexpensive lighting system.
