You could do something similar to what the MergeThreshold option in vision.CascadeObjectDetector does. The algorithm used is described in brief here:
Look under Algorithms for Merge Detection Threshold.
Essentially, you could do something like this:
If two bounding boxes overlap significantly, merge them by computing the merged bounding box at the mid point of the two detections, with size as the average of the sizes of the individual detections. You can use bboxOverlapRatio to compute the overlap ratio.

Add the box width minus 1 to get the final box index. Now take the minimum of the left coordinates and the maximum of the right coordinates to do a horizontal merge. Likewise minimum of bottom and maximum of top to do a vertical merge. You can convert those back to widths and heights if you want: subtract left from right and add 1 to get the width.
