Annotation tool

We carefully designed the UX of the annotation tool from the ground-up to make annotating as simple and efficient as possible.

Remo currently supports three types of annotations:

  • Image level annotation for image classification tasks
  • Bounding boxes for object detection tasks
  • Polygons for segmentations tasks

Efficient Annotation tools

Following the approach defined in the paper Extreme click for efficient object detection, we implemented the efficient annotation method "xclick", which should yield a speedup of up to 5x compared to the traditional "draw a box" annotation.

Annotation tool shortcuts

To facilitate annotation, the annotation tool features a number of shortcuts to the most common functionalities.
