Average Precision Values [Eq. (8)], Averaged for All Sequence Frames, Obtained for the Human Target [Whose Ground-Truth is Shown in Fig. 1(b)] in Different Imaging Conditions and Video Types (Sample Frames of These Videos Are Shown in Fig. 2) Using the Median Filter for Background Estimation (Subsection 3A) and Using the Nonparametric Model [23, 24] for Background Estimation; The Average Recall Value [Eq. (7)] in All Cases Was Set to the Same Value (0.99 in Our Implementation)
| Video Type Imaging Conditions | Degraded | Restored (with Estimated PSF) | Restored (with True PSF) |
|---|
| Using the median filter |
| Low noise and high blur | 0.33 | 0.52 | 0.54 |
| High noise and high blur | 0.32 | 0.39 | 0.40 |
| Low noise and low blur | 0.63 | 0.92 | 0.97 |
| High noise and low blur | 0.61 | 0.63 | 0.67 |
| Using the nonparametric model |
| Low noise and high blur | 0.38 | 0.56 | 0.57 |
| High noise and high blur | 0.35 | 0.41 | 0.42 |
| Low noise and low blur | 0.70 | 0.96 | 0.99 |
| High noise and low blur | 0.68 | 0.69 | 0.73 |

| Video Type Imaging Conditions | Degraded | Restored (with Estimated PSF) | Restored (with True PSF) |
|---|
| Using the median filter |
| Low noise and high blur | 0.76 | 0.86 | 0.86 |
| High noise and high blur | 0.73 | 0.75 | 0.76 |
| Low noise and low blur | 0.96 | 0.99 | 1.0 |
| High noise and low blur | 0.94 | 0.95 | 0.96 |
| Using the nonparametric model |
| Low noise and high blur | 0.75 | 0.86 | 0.87 |
| High noise and high blur | 0.72 | 0.74 | 0.75 |
| Low noise and low blur | 0.96 | 0.99 | 1.0 |
| High noise and low blur | 0.95 | 0.95 | 0.95 |

|---|
| 1 | 40.76 | 55.20 |
| 2 | 41.32 | 45.73 |
