It is used to set parameters of feature match in order to set search space. The targets in specific
search space can be searched only, as shown below.
(1) Basic Parameters
All Search Mode: all the templates are matched after enabling and output the optimal
results.
Min. Match Score: the match score means the similarity between feature template and
target in searched images. It is also called as similarity threshold. Only when the target's similarity
reaches similarity threshold, it can be searched out. The max. value is 1 which means totally matched,
and it is 0.5 by default.
Max. Match Number: it is the max. target quantity can be searched. It is 1 by default and
the range is 1 to 200.
Match Polarity: polarity means the color transition from feature image to background.
When the edge polarity of the searched target does not match with feature template polarity, but you
want to make sure the target is searched, then you need to set match polarity as ignored. if not, you
can set as considered, and search time can be reduced.
Angle Range: it means the angle changing range when comparing the target and created
template. If you want to search the proactive target, and then you need to set respectively, and the
default range is -180° to 180°.
Scale Range: it means scale changing range when comparing the target and created
template. If you want to search the target with same scale changing, and then you need to set
respectively, and the default range is 1.0 to 1.0.
(2) Advanced Parameters
Max. Overlap Rate: when searching for multiple targets, two detected targets overlapping
with each other, and the maximum overlap ratio allowed by the matching frames is overlap threshold.
The larger the value, the greater the degree of overlapping between the two targets. The range is 0°
to 100° and it is 50 by default.
Sort:
- Sort by score in descending order: sorted by the score of the feature match in
descending order.
- Sort by angle in descending order: in descending order of relative angular deviation
in the current result.
