Terminology¶
The BrainFrame documentation uses terms that are common in video analytics but may have different meanings in other fields. We also use a few generic terms to describe specific BrainFrame concepts. If you are new to video analytics or are ever confused by a term, please take a look at this guide.
Term | Meaning |
---|---|
Stream | The live stream that is being fed to the Client or to the Server. A stream is video of some sort, from a video file, webcam, or IP camera. |
Detection | Any machine learning detection. A detection is a "bounding box", and has a label (person, car, dog, etc). |
Region | An area on-screen that has been configured by the user. It could be a door, an area on the floor, etc. The server will automatically count detections in that region. |
