Table 3.

For each feature detector, food table, and image size this table shows the number and percent of frames where a bird was detected with no bird present

Detector	Frames without birds and false positives	Percentage of frames without birds and false positives (%)	Frames with birds and true positives	Percentage of frames with birds and true positives (%)

It also shows the percent and number of frames with true‐positive detections using an IoU threshold of 0.5 when birds were in the frame.
