For this demo, we are going to capture frames from a webcam in real-time and use a DNN to detect and classify 20 kinds of objects that may be in any given frame. Yes, a single DNN can do all this in real-time on a typical laptop that a programmer might use!
Before delving into the code, let's introduce the DNN that we will use. It is a Caffe version of a model called MobileNet-SSD, which uses a hybrid of a framework from Google called MobileNet and another framework called Single Shot Detector (SSD) MultiBox. The latter framework has a GitHub repository at https://github.com/weiliu89/caffe/tree/ssd/. The training technique for the Caffe version of MobileNet-SSD is provided by a project on GitHub at https://github.com/chuanqi305/MobileNet-SSD/. Copies of the following MobileNet-SSD files can be found in this book&apos...
