名称
set_reference_templateT_set_reference_templateSetReferenceTemplateSetReferenceTemplateset_reference_template — Define reference position for a matching template.
警告
set_reference_templateset_reference_templateSetReferenceTemplateSetReferenceTemplateSetReferenceTemplateset_reference_template is obsolete and is only provided for
reasons of backward compatibility. New applications should use the
shape-based or NCC-based operators instead.
参数签名
Herror T_set_reference_template(const Htuple TemplateID, const Htuple Row, const Htuple Column)
描述
set_reference_templateset_reference_templateSetReferenceTemplateSetReferenceTemplateSetReferenceTemplateset_reference_template allows to define
a new reference position for a template.
As default after calling create_templatecreate_templateCreateTemplateCreateTemplateCreateTemplatecreate_template or
create_template_rotcreate_template_rotCreateTemplateRotCreateTemplateRotCreateTemplateRotcreate_template_rot
the center of gravity of the template is used.
Using set_reference_templateset_reference_templateSetReferenceTemplateSetReferenceTemplateSetReferenceTemplateset_reference_template the reference position can
be redefined. In the case of the center of gravity as
reference the vector (0,0) is returned after matching
for a null translation of the pattern relative to the image.
