Keypoint annotation - Vision


Is it possible to do keypoint annotations on images with Prodigy? I see there is bbox, poly and lasso out of the box. Since it's not supported by default, is it possible to define a custom type of annotation? If so, has anyone done it before and can give me a few hints?

Thanks a bunch!

Hi! By keypoint annotation, do you mean annotating specific points on an image? There's no separate annotation mode for just points but depending on the task, one solution could be to use the regular bounding box and enable visualising the center point with show_bounding_box_center: You can also set image_manual_from_center to enable drawing from the center if that feels more natural. And you can customise the box to make it less prominent if needed. The underlying data will include the center coordinates so you can always use this data as the final output.
