 ## Predict proposal region
 RPN is used separately to propose regions, feed an any size image to RPN, it will generate height\*width\*9 outputs, each output have two siblings, one is score between [0,1] represent probability of fg/bg, and another is 4 transformed values, we need do some work to process this output to bounding box proposals.
 
-In the next part, let's see how the use RPN predict result to do the real object detection task.
