Image-Based Framework for Concrete Surface Crack Monitoring and Quantification
Figure 10
Concrete surface at different acquisition times: (a) at 0 second (the first frame with dividing grids of the image domain); (b) at 0.625 second (the th frame); (c) at 0.65 second (the th frame at which the first crack appeared); (d) at 0.80 second (the rd frame); (e) at 1.20 seconds (the th frame); (f) at 1.85 second (the 70th frame). In (a), the subdivisions for the image domain are overlaid with the image.
