[technolojin]

Description

Implement same fix of PR #9595

Related links

1. fix non-maximum suppression target decision logic
   Before: If both of the object class are in the target label, caluclate IoU. If not, check distance and calculate IoU if the distance is less than a threshold.
   After: If the label pair is not the same and one of them is pedestrian, do not suppress. Then, check distance and calcuclate IoU only if the distance is within a threshold.

2. optimize non-maximum suppression search range
   Keep the squared value of the distance threshold.

3. remove NMS type
   Since there is no other NMS option, remove the logic and parameter to select NMS type.
