Check Display results to have the measurements for each particle displayed in the ImageJ worksheet. Bins is the number of bins used for the particle size distribution histogram. Particles smaller than Minimum Size or larger than Maximum Size are ignored. Use Image/Adjust/Threshold to threshold an image. It then outlines the object using the wand tool, measures it using the Measure command, fills it to make it invisible, then resumes scanning until it reaches the end of the image or selection. It works by scanning the image or selection until it finds the edge of an object. This command counts and measures objects in binary or thresholded images. The width of the worksheet columns can be adjusted by clicking on and dragging the vertical lines that separate the column headings. You can also save measurements by right-clicking (control-clicking on a Macintosh) in the worksheet and selecting Save As or Copy from the popup menu. To export the measurements as a tab-delimited text file, use File/Save As/Measurements or select one or more lines (shift-click to extend the selection) and use Edit/Copy (C) or Edit/Cut (X). Use the Analyze/Measurement Options to specify what area statistics are recorded. Calculates line length if a line selection has been created using one of the three line selection tools. Area statistics are calculated if there is no selection or if a subregion of the image has been selected using one of the first four tools in the tool bar. Based on the selection type, calculates and displays either area statistics or line lengths.
