Sensor-based sorting provides state-of-the-art solutions for sorting of cohesive, granular materials. Systems are
tailored to a task at hand, for instance by means of sensors and
implementation of data analysis. Conventional systems utilize
scanning sensors which do not allow for extraction of motionrelated information of objects contained in a material feed. Recently, usage of area-scan cameras to overcome this disadvantage
has been proposed. Multitarget tracking can then be used in order to accurately estimate the point in time and position at which
any object will reach the separation stage. In this paper, utilizing
motion information of objects which can be retrieved from multitarget tracking for the purpose of classification is proposed. Results show that corresponding features can significantly increase
classification performance and eventually decrease the detection
error of a sorting system.
