深度學習CNN用於目標檢測的方法總結

The improvement of Fast R-CNN over SPPnetillustrates that even though Fast R-CNN uses single-scale training and testing,fine-tuning the conv layers provides a large improvement in mAP (from 63.1% to66.9%). Traditional R-CNN achieves a mAP of 66.0%. These results arepragmatically valuable given how much faster and easier Fast R-CNN is to trainand test, which we discuss next.
