Fuzzy logic strategy for adjusting image fuzzy degree.
| Feature category | Level | Membership value | Fuzzy degree adjustment strategy |
|---|---|---|---|
| Contrast | High Contrast | 0.8 – 1.0 | Decrease blurring to preserve more details |
| Medium Contrast | 0.4 – 0.8 | Apply moderate blurring to balance details and noise | |
| Low Contrast | 0.0 – 0.4 | Increase blurring to reduce noise | |
| Edge Strength | Strong Edges | 0.7 – 1.0 | Apply lower blurring to preserve edge details |
| Medium Edges | 0.3 – 0.7 | Apply moderate blurring to smooth edge transitions | |
| Weak Edges | 0.0 – 0.3 | Apply higher blurring to enhance transition areas | |
| Texture Complexity | Rich Texture | 0.7 – 1.0 | Apply lower blurring to enhance details |
| Medium Texture | 0.4 – 0.7 | Apply moderate blurring to balance details and noise | |
| Simple Texture | 0.0 – 0.4 | Apply higher blurring to reduce unnecessary detail enhancement |
