Abstract: Add/Edit. object detection. Instead of using sliding window, SSD divides the image using a grid and have each grid cell be responsible for detecting objects in that region of the image. The task of object detection is to identify "what" objects are inside of an image and "where" they are.Given an input image, the algorithm outputs a list of objects, each associated with a class label and location (usually in the form of bounding box coordinates). This functionality is similar to dlib. SSD speeds up the process by eliminating the need for a region proposal network. The SSD approach is based on a feed-forward convolutional network that produces a fixed-size collection of bounding boxes and scores for the presence of object class . From a purely python perspective it's not understanding your class name 'models'. After a moment, you should see a new window pop up, giving you a feed of the Pi camera or .
