Measurements

The Measurements group allows you to select the measurement data you want to collect for the tracks identified by the Measurements tools. For example, you can obtain area, distance, angle, and many other kinds of measurements based on the nature of your objects of interest.

Measurement data is returned and display in the Image-Pro Data Table.

Options: Click on the Options tool to access the Measurement Options dialog box which allows you to change the display characteristics of your measurements. Click here for more information.

Types: Click on the Types tool to display the Measurements dialog box. This dialog box show a sortable list of measurements available for selection in the left-most panel (titled "Available Measurements"). Measurements can be selected by adding them to the list in the right-most panel (titled "Selected Measurements").

Use the two pull-down list boxes at the top of the Available Measurements panel to filter the list of available measurements. The left-most pull-down list box allows you to filter the available measurements list to show only those measurements applicable to a certain kind of feature. Not all measurements are applicable for all features. For example, an Area measurement is not applicable to a line-type feature, and a Length measurement is not applicable to a region-type feature. In the left-most pull-down list box, select the type of feature that you want to select measurements for. If you want to see all measurements, select "All Types."

The right-most pull-down list box allows you to filter the available measurements list to show only those measurements belonging to a selected category. For example, you can limit the list to only those measurements related to Density analysis, Shape analysis, or Holes analysis. If you want to see all measurements, select "All Categories."

A description of each measurement can be accessed using the Image-Pro tooltips feature. Simply position your mouse over the name of the measurement in the Available Measurements panel, and view the tooltip for that measurement.

Note that the Minimum and Maximum columns in the right-side panel can be used to define a range of values to filter on for the associated measurement type. The range defined here can be used to filter your threshold segmentation results. These fields are only available if the Filter checkbox for the corresponding measurement type is checked in the Selected Measurements/Filters Panel. For example:

Load: Click this tool to load previously saved measurements settings and options.

Save: Click this tool to save the currently configured measurements settings and options to a file. The file can then be loaded at a later time to restore the settings in a new session.

Reset: Click this tool to reset all configured measurements settings and options to their factory defaults.
