WebAug 2, 2024 · In thresholding operations, you convert grayscale images to binary (black and white) images based on the threshold value. The pixels with intensity values greater than the threshold are assigned white, and the pixels with intensity values lower than the threshold are assigned a dark value. WebVarious white-box methods can be used to segment an image of a crack into a binary cracked and uncracked pixel image. Algorithms broadly fall into the categories of edge-based (e.g. Canny edge detector or Wavelet transform), and threshold-based (e.g. Otsu thresholding) [7]. Despite their effectiveness, these methods also detect many false ...
