Detailed Description
Region centred on a single point, pose defined by other pts.
Region defined by three points, p0=pts[i0], p1, p2. The region is centred on p0. Bounding box of region is aligned with the vector (p2-p1), and its width and height are defined relative to |p2-p1|
Parameters in text file:
{ i0: 5 i1: 31 i2: 37 rel_wi: 0.5 rel_wj: 0.2 form: box }
