Vision
What is object detection?
Object detection finds instances of objects in an image or frame and returns boxes, usually with a class and a score.

How it works
- The model reads a frame.
- It writes boxes and labels.
- Those labels are stored on the frame row.
What it is not
It is not classification of the whole picture, and it is not semantic search without boxes.
object detection: this, and the thing it is confused with
| This | Not this | |
|---|---|---|
| Output | Boxes and classes | One label for the whole image |
| Location | Where in the frame | Only that something exists |
| Search | Frames that contain a class | A similar picture with no box |
Where Pixeltable fits
Pixeltable assigns a detector such as YOLOX on the frame column of a video view.
