Results view - Class Measurements

Use the Class Measurements results view in the Count and Measure Results tool window to have the results for classes of objects shown.

Use the View > Tool Windows > Count and Measure Results command to have the tool window displayed. Should the Class Measurements results view not yet be active, click the Class Measurement tab to activate it.

Structure of the tool window

The tool window is made up of several groups. Click on one of the areas in the tool window shown schematically above to jump to the corresponding help topic.

(1) Toolbar in the results view

In the Class Measurements results view, you can find a toolbar with the following buttons.

	Select Detected Objects	Click this button to select an individual object, or also several objects.
	Toggle Object Filter	Click this button to switch the current object filter on or off.

Select Class Measurements

Click this button to select the measurement parameters for the object classes that you want to output in the results sheet.

When you perform an object analysis on ROIs you can also find parameters here that apply to ROIs, the name of the ROI for example.

Export to Excel

Click this button to export the results to an Excel sheet.

(2) Results for the object classes

Sizes classes are an example for possible objects classes. Each detected object is assigned to a class due to its size.

Another example for object classes is a classification scheme for the phase. All objects belonging to one phase due to the current threshold value settings form their own class.

When you switch on the filter function, only the objects that lie within the defined filter range, will be taken into account.

Structure of the results sheet

In the column's header, you'll see the name of the measurement parameter. In the cells below it you can find the results for the class measurements. Use the Select Class Measurements dialog box to select the class measurements that are to be displayed.

The number of measurements that will be output depends on a variety of factors, such as the image type, the number of classes, and the settings in the options.

Within a column, there is always only one unit for all of the measurement values. This unit depends on the calibration of the active image or the active layer. When you accumulate data from several images, the smallest unit from all of the images will automatically be used. You can consolidate the measurement values for all of the images that have been calibrated in the same basic unit, in meters for example. It is not possible to accumulate the measurement values of images that have been calibrated in different basic units, length and pixels for example.

The order of the columns can't be changed in the results view. It is preset by the succession of the measurement parameter in the Select Class Measurements dialog box, and can only be changed there.

Sorting the results sheet by a measurement parameter

You can sort the results sheet according to a particular measurement parameter. To do this, double click on the header of the column that contains the required measurement parameter. The measurement values in the sheet will then be sorted in ascending or descending order. Double click the header of the column again to sort the measurement values in the reverse order. An arrow in the header will show you the direction in which they are sorted.

Results of ROI measurements

You can limit an automatic image analysis to a certain segment of the image. The analysis will then only be performed on this image segment.

When you've performed one of these analyses on ROIs, some of the results are shown in the Class Measurements results view.

To do this, select the Show class results per ROI check box. Now the results for this view are displayed separately for each ROI. You can find the check box in the Tools > Options > Measurement and ROI > Results dialog box.

(3) Statistics

Below the class results for the measurement parameters you will find the results sheet with the statistics. The statistics will be shown for the active measurement parameter for all classes. When you have chosen the Mean parameter, for example, the mean value for the active measurement parameter will be output. You can completely switch of the display of the statistical parameters, or also select only certain parameters. Open the Options > Count and Measure Results dialog box to make these settings.
