Fast Corners Extensions

Adds various extensions to the Fast Corners vision function.

This section describes different extensions to the standard Fast Corners vision function.

Supported Output Formats

In addition to standard formats for the Harris Corners primitive, VisionWorks supports the following output array formats:

For the NVX_TYPE_POINT2F type only corner coordinates are provided without strength information.

The output array capacity must be explicitly provided, even for virtual arrays.

Strength computation

The primitive calculates strengths for output keypoints only if non-max suppression is requested (nonmax_suppression flag is set to true); otherwise, the strength value for output keypoints will be set to zero.
