Detailed Description

The Harris corner detector.

Parameters :

• corner_count_max - maximum no of corners required.
• gauss_sigma - sigma for the Gaussian smoothing.
• relative minimum - a guidance term: first attempt will be to collect all corners whose corner strength is greater than (max strength * relative minimum).
• scale factor - the 'k' from the Harris auto-correlation expression.

    Modifications:
     First version generated from C code with minimal modification for C++/TargetJr data structures.
     P.Vanroose  Mar97  corrected memory management (point_list_ & *free_*())
     P.Vanroose  Aug97  point_list_ now safer (added AddPoint(); SetPointList() out of use now)
     J.Mundy     Jan98  slight modified the interface to correspond to new style using parameter blocks and image dispatch
