We improved the YOLOv5 detection method in three ways: 1) a new feature fusion layer has
been added to capture more shallow feature information of small size pedestrians, 2)
features from the backbone network have been brought into the feature fusion layers to
reduce feature information loss of small size pedestrians; and 3) Scale Invariant Cross-stage
Partial Network (SCSP) has been added to detect the pose and scale invariant pedestrians …
