The Labelling Task

You will be shown sketches containing overdrawn strokes. Some of these overdrawn strokes can be grouped together to depict the same clean curve (see the example below). For each sketch, take your time to observe and mentally group the strokes. When ready, you will see a grouping of the same sketch indicated by different colors. Your task is to modify this grouping to match the grouping constructed in your mind.

You will be shown sketches containing overdrawn strokes. Some of these overdrawn strokes can be grouped together to depict the same clean curve (see the example below). For each sketch, take your time to observe and mentally group the strokes. When ready, you will see the sketch in gray. Your task is to interactively group strokes in this sketch match the grouping constructed in your mind. The grouping you created will be indicated by different colors. You can modify the grouping as many times as you want.
