Renet: An improvement method for remote object detection based on Darknet.

Recently, when we used this method to identify aircraft targets in remote sensing images, we found that there are some defects in our own YOLOv2 and Darknet-19 network. Characteristic in the images we identified are not very clear,thats why we couldn't get some much more good results. Then we replaced the maxpooling in the yolov3 network as the global maxpooling.Under the same test conditions, we got a higher It achieves the processing speed of a single image is only 0.023 s on a GTX1050TI.
