Early Pest Detection in Greenhouses

We promote in situ early pest detection in greenhouses based on video analysis. Our target application is the detection of bio-aggressors on plant organs such as leaves. The goal of this work is to define an innovative decision support system, which handles multi camera data and follows a generic approach to adapt to different categories of bioaggressors. This approach is non-destructive and no...
