The task has ended because we detected that your outlines are not precise enough.

Please remember to be as precise as possible on the elements you choose to highlight. Follow the contours of the element and don't add unecessarily large margins. On text, do not highlight individual letters unless they stand out from the rest of the letters in that word. If you're having trouble with the default tool (Stroke Fill), please switch to Polygon Fill by clicking on the corresponding button on the right column of the task. Polygon Fill is a bit slower but allows for greater control and precision.
Make sure to do at least one annotation per image.
