![]() ![]() Using the Threshold tool can provide a very good rough segmentation of the region of interest, but may require some editing. The threshold range and histogram can also be based on a logarithmic scale (more homogenous) or linear scale. The threshold range will also be shown with the image histogram in the tool window. The opacity of this preview can be set using the provided slider. A preview of the threshold regions will be displayed in the 2D viewers (can be disabled in the tool window). The threshold range can be set in two ways: the slider provided in the tool window will set the maximum and minimum for thresholding or seed points can be placed throughout the volume and the values at those points will set the range to threshold. This is one of the most basic semi-automatic tools used in segmentation as it is fast but can also separate contrasted regions very effectively. The mask layer created will be a segmentation of the regions in the image data that have intensities in the range specified. The Threshold tool generates a mask label from an image data volume and the value range to select. This tool generates a mask label from an image data volute and the value range to select.
