abstract = "Because of the impact of the variation in different
concrete surface images, such as the heterogeneity of
the detection environment, uneven illumination, stains,
the block, and water leakage, the existing crack
detection algorithms cannot detect the real crack
quickly and effectively. In this paper, a genetic
algorithm based on genetic programming (GP) and
percolation model is proposed. This method involves
three steps. First, the cracks are pre-extracted by the
image processing model of GP. Second, the crack tip is
calculated after the crack skeleton is extracted. With
the endpoint as the anchor point, high speed, and high
precision percolation are used to detect the cracks
with small width accurately. Concurrently, the fracture
unit areas are scanned for connection. Finally, the
preextracted cracks are connected with the cracks
detected by the percolation, and the mass interference
area is removed to obtain the real cracks on the
concrete surface. The simulation results show that the
concrete surface crack detection algorithm based on the
GP and percolation model can effectively combine both
of their advantages. The algorithm proposed in this
paper can detect real concrete surface cracks
accurately and effectively with strong robustness.",
