Use the Threshold window to remove all data in an image that is below a certain intensity cutoff value. The output may be either the image values above the threshold or a binary mask, where all pixels below the cutoff are 0 and all above are set to 1.
Open the Threshold window by choosing Filter | Threshold from the main softWoRx menu.

Choose one of the following modes:Data creates an output image of all intensities equal to or above the threshold (the cutoff intensity value). If a pixel has an intensity value below the threshold, the pixel in the output image is set to this value (usually 0).Mask puts zeros in all pixels where the intensity is below the threshold and ones for all pixels equal to or above the threshold. |
