Single shot detectors: remarks

There are different approaches to object detection using CNNs. Roughly speaking, the most popular ones are:

• One-stage detectors, also known as single shot detectors. Most famous algorithm: YOLO. 
• Two-stage detectors. Most famous algorithm: Faster RCNN. 

In this course, we focus on single shot detectors and describe the ideas and principles behind, e.g., the YOLO algorithm. The difference in performance between one- and two-stage detectors are not generally very big, but one-stage tend to be faster whereas two-stage are more accurate. 

We have produced one video for training and one for testing, since the techniques that the single shot detectors use to handle the set of predictions differ between training and testing.
