By using SSD, we only need to take one single shot to detect multiple objects within the image, while regional proposal network (RPN) based approaches such as R-CNN series that need two shots, one for generating region proposals, one for detecting the object of each proposal. Thus, SSD is much faster compared with two-shot RPN-based approaches.
I used the dnn module (Deep Neural Networks) of OpenCV for loading the caffe and prototxt files.
I found the MobileNetSSD_deploy.prototxt.txt and MobileNetSSD_deploy.caffemodel pre-trained weight files from the https://awesomeopensource.com/project/chuanqi305/MobileNet-SSD
