Are you using the latest version? I tried with your image but no false postives detected with score_threshold=0.99f (default was 0.5f):

detection_output(mbox_priorbox, mbox_loc, mbox_conf, mbox_iou, 0.3f, 0.99f, 1000, 100, facesInfo);

link to the above line

@fengyuentau Firstly, thanks for the reply, i am not using latest version, and i checked latest model , no false positive is detected now.

My quesiotn is more like a generic question, as i understand false positive is anyway possible, and i did see false positive with latest model on other pictures.

I can upload the file if needed.
