Description
Summary:•A simple and low-cost computer vision system to classify yellow melon at harvest time.•The method classifies yellow melon based on the soluble solids content (sweetness).•The method classifies in two classes: “suitable” or “unsuitable” for harvesting.•Melon growers anywhere may apply the model as it can be embedded in mobile devices.•The model has good sensitivity and specificity by Receiver Operation Characteristic. This paper presents a Computer Vision (CV) approach to harvest decision of yellow melon (hybrid Natal®) based on prediction of Soluble Solids Content (SSC, as °Brix) from digital image. At this point, it is worth remembering that the minimum SSC for harvesting this type of melon is 9°Brix. In this context, melons with SSC ≥ 9°Brix should be classified as “suitable for harvesting” (SFH), whereas melons with SCC
