Abstract

Ranging the crates of grapes using a robust quality index is a major tool for operators during the Champagne grape harvest. We propose building such an index by processing RGB images of crates of grapes. Each image is segmented into six classes such as healthy grape, crate, diseases (grey rot, powdery mildew, conidia), green elements (stalk, leaf, unripe healthy grape), shadow, dry elements (dry leaf, dry grape, wood) and the index of quality reflects the proportion of healthy part inside the crate. As the main pretreatment, the segmentation must be carefully performed, and a random forest-based solution for each variety of grape is proposed here whose training is done on hand-tagged pixels.
