The upper black rectangle represents the target wall surface. Within the dashed box, the blue, yellow, and green curves correspond to three partial edge curves of the target brick missing area awaiting aggregation. The dark blue dashed line guides to the magnified aggregation process below. The lower solid black line represents the enlarged dashed box area, while the black dotted line indicates omitted brick missing regions.
