6. When continuity fails
A vision algorithm groups every smooth curve in a photograph into a single object, using the principle of continuity. On a busy portrait it merges a finger contour with the outline of a lip because the two curves align perfectly. What does this failure teach?
7. Which cue wins on support
A doctored photograph shows a ball with its drop shadow far to the side while a slack string drapes from the ball to the ground surface. The two support cues disagree. Which reading does the combination most strongly support, and why?
