What is image annotation?

Image annotation is human or model labels — boxes, captions, classes — stored on visual rows so training and review can reuse them.

Updated

How it works

  • The image or frame is the row.
  • A person or a model writes labels onto that row.
  • Training and review read the same rows.

What it is not

It is not a labeling product that never runs your models, and it is not labels trapped in an export file.

Where Pixeltable fits

Pixeltable stores labels as columns beside the image. A labeling tool can still be where people draw; the table is where the labels stay.
