Remarks

The line angle search range is centered on the xRotation of affine rectangle used as the ROI for the segmenter. In other words, the full search range is xRotation - AngleHalfRange, xRotation + AngleHalfRange].

Increasing AngleHalfRange increases the segmenter's run time.

Setting AngleHalfRange to 0 effectively disables angle search.
