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 ...

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 ...

In some vitrous substances, when heated, not one, but two physical mechanisms are responsible for crystallization, as scientists have discovered. The first-time use of numerical image processing to ...
