Fig. 8From: A method to calculate the number of wheat seedlings in the 1st to the 3rd leaf growth stagesValidation results of seedling counting model of different densities and leaf ages. The datasets are these images for model validation (720 observations), and each treatment has 60 data. The densities of images from the first line to the fourthly are 75 × 104 plants ha−1, 150 × 104 plants ha−1, 225 × 104 plants ha−1, 300 × 104 plants ha−1Back to article page
