Otsu binary threshold
WebThereafter, the resultant crack patches are binarized based on grayscale intensity using an Otsu's thresholding method [51] which is aimed at computing an optimal intensity threshold by minimizing intraclass variances. The group of pixels with an intensity value lower than the threshold, P I, is identified as shown by the red points (1205). Webotsu is a great way to threshold images into binary classes. Traditional otsu is designed for binary thresholding but many images contain multiple regions to...
