Fig. 6From: Soybean leaf estimation based on RGB images and machine learning methodsGrowth dynamics of soybean leaf parameters under the RF model. Take one of the varieties, for example. MC: soybean monoculture; IC: maize‒soybean relay strip intercropping. The red line indicates the time of the last image collection before the maize harvest, and both R2 and MAE are averagesBack to article page
