Chili is a spice of major importance in the Sri Lankan cuisine, resulting in a high demand for chili cultivation. However, chili plants frequently become infected by a viral disease resulting in curly leaves which makes them unusable. The students combined a camera system with a machine learner for the automatic detection of change of the leaves' appearance in order to provide early warning of a virus outbreak. In this way, infected plants can be removed in time in order to avoid a transfer of the disease to neighboring plants.
