WebGo to Analyse -> Set Measurements. In the Set Measurements window you can choose what you want to measure by clicking on or off the checkboxes beside different parameters. Here we will turn on Area only. Ensure you also have Limit to threshold selected in the options so that FIJI does not measure the entire image. WebThresholding is done by choosing a pixel intensity value above which the pixel will be rated as belonging to a particle, below this it will be set as background. In this work, the threshold value is determined visually. Several object parameters can be calculated, the most common ones being the area and mean intensity.

WebIn other words, a threshold is set at the maximum value minus noise tolerance and the contiguous area around the maximum above the threshold is analyzed. For accepting a maximum, this area must not contain any point with a value higher than the maximum. Only one maximum within this area is accepted.
