McGET: A rapid image-based method to determine the ...

The gravel coverage of McGET was calculated based on the proportion of gravel pixels in the image, while the gravel coverage of field measurement was estimated by line transect method. The total number of 7422 gravels from eighteen images randomly selected from each site was manually outlined using ImageJ 1.50c (National Institutes of Health, USA).

rescaled to 8-bit values (0–255) to make it compatible with standard image processing algorithms. Basic grey-level thresholding methods can then be applied to segment objects in the texture image. For example, Figure 2A shows the texture image calculated for the image in Figure 1A, and Figure 2B shows the associated histogram.

Automated extraction of grain-size data from gravel ...

This paper describes and tests a method for the automated extraction of grain-size data from digital imagery. It combines two basic image processing methods for this purpose: grey-scale thresholding to create a binary image and watershed segmentation to grow edges on the binary image to allow the identification of individual grains. The method is subject to rigorous testing in terms of edge ...
