Software can control or guide direction selection at frame or sequence level as shown in Figure 5-8.
Figure 7-56 Software Controlled Direction SelectionTable 7-105 summarizes number of option available to software.
| Mode | Name | Details |
|---|---|---|
| 0 | Horizontal | Dir = 0 |
| 1 | Vertical | Dir = 1 |
| 2 | HV | Dir = 2 |
| 3 | HV_Threshold (Fixed threshold is MMR) | in Dir = 0: gradH ≥ gradV + threshold in Dir = 1: gradV ≥ gradH + threshold in Dir = 2: Otherwise |
| 4 | HV_AdaptiveThreshold | in Dir = 0: gradH ≥ gradV + threshold in Dir = 1: gradV ≥ gradH + threshold in Dir = 2: Otherwise |
For calculation of adaptive threshold, 7 options are used. Each one defines a threshold to be used as a different intensity level as it follows:
The adaptive threshold can then be calculated as a linear interpolation between 2 successive entries based on the given intensity.
