Table 9 Classification table for Apple leaf Diseases
From: Apple leaf disease severity grading based on deep learning and the DRL-Watershed algorithm
Plaque Level | Description | The Range of k |
|---|---|---|
Level 0 | No lesions present | 0 ≤ k ≤ 0.01% |
Level 1 | Lesion area constitutes less than 5% of the total leaf area | 0.01%< k ≤ 5% |
Level 3 | Lesion area accounts for 5–10% of the total leaf area | 5%< k ≤ 10% |
Level 5 | Lesion area represents 10–25% of the total leaf area | 10%< k ≤ 25% |
Level 7 | Lesion area covers 25–50% of the total leaf area | 25%< k ≤ 50% |
Level 9 | Lesion area exceeds 50% of the total leaf area | 50%< k |
