Experiments based on 166 test images show that the proposed method can achieve better performance measured by F-measure, which takes both precision and recall rates into consideration. Finally, 10 detection results from two grid cell images are combined and denoised to obtain final results. ![]() Third, connect scattered seeds by an optimal path searching process considering grayscale values, cell direction and proximity. Second, extract 10 images of crack seeds through symmetry check and grayscale verification. It has four steps: First, generate two partly overlapped images with 8×8 pixel grid cells. Taking advantages of the state-of-the-art 3D image acquisition technology, this paper proposes a novel crack detection algorithm. The contract includes product in electronic form. 3D pavement images have obvious advantages over 2D images in dealing with disturbances caused by lane markings, sun-light shadows, oil marks and debris. MultiExtractor License activation License Activation How to activate the program To activate the software, you must place your order. But we are still short of a robust method, which can generate satisfied results on general cases. ![]() 2D image-based crack detection has been studied for many years.
