We used a novel voice-triggered data collection system to measure human participants' ability to quickly name objects represented by modified line drawings. Remarkably, we find that shifting added noise contours by even a few pixels can have a devastating effect on object recognition ability if that noise contours form an "L-junction". The labeled image shown here demonstrates how powerful different kinds of vertices and junctions are in guiding our perception of coherent volumes.
