What is "Object detection" ?

I'm in the situation I have to implement paper that is about object detection.

That makes me so interesting ...but the problem is ..time is short 

So i started researching about this area.

 

Summary of what i learned

 

Object detection = Localization + classification

 

In doing this , There're two kind of methods

1. 1-stage method (simultaneously)

2. 2-stage method (classification after getting resional info(resion proposal)

 

Measurement

1. IoU (Intersection over Unit)

2. mAP (mean average Precision) 

3. FPS
