Software can control or guide direction selection at frame or sequence level as shown in Table 10-62.
Table 10-239 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.
