Figure 6From: Discrete shearlet transform on GPU with applications in anomaly detection and denoisingCrack detection results. (a) Using shearlet coefficients (Shearlet-C), (b) using thresholding in the image reconstructed using shearlets (Shearlet-I), (c) using intensity thresholding in the original image (d), and using Canny edge detection. All results are generated at peak F2 score.Back to article page
