Thresholding is the process that converts a micrograph into a binary black and white image, corresponding to particle and background. It does so by setting a threshold for pixel brightness. “Image ...
Abstract X-ray computed tomography is an efficient method for quantitatively estimating the characteristics and heterogeneity of shales in three dimensions. A threshold is commonly used to separate ...
Wavelet threshold algorithms replace small magnitude wavelet coefficients with zero and keep or shrink the other coefficients. This is basically a local procedure, because wavelet coefficients ...
