Measure

Measure > Perform Measurement

(requires: Automatic Measurement)

Performs the automatic object measurement. The segmented image (the current binary layer) is scanned and a set of size, shape, color and density features is measured. The set of features is defined by the Measure > Object Features command.

Note

If the measurement ROI or measurement frame are turned ON, or measurement restrictions are set, all these settings are taken into account.

Measure > Measure Objects

(requires: Automatic Measurement)

This command performs the object measurement. The detected objects are indicated by a green outline. The measured data are inserted into the Automated Measurement Results window.

Measure > Measure Field and ROIs

(requires: Automatic Measurement)

Performs automatic field measurement.

Note

A set of size, shape and density measurements defined by the Field Features command is performed on a field. Performing this command, the MeasureField is called and appended to the list of executed functions.

Measure > Object Features

(requires: Automatic Measurement)

Enables you to select features to be measured. The description of each measurement feature can be found in the Measurement Features chapter.

Features

Check this item to display the thumbnails in Object Catalog control.

OK

After you click OK, first the low level function ResetObjectFeatures and then several functions SelectObjectFeature are called and appended to the list of executed functions. The number of SelectObjectFeature functions is equal to the number of selected features in the dialog box.

Measure > Field and ROI Features

This command opens the View > Analysis Controls > Annotations and Measurements control window and activates the 3D length tool. See Measurement Tools.

Measure > Intensity Profile

Enables interactive profile measurement. The Intensity Profile control window appears and the arrow indicating the profile cross section is displayed in the image.

Graph/Data/Measurement Tabs

There are three tabs at the bottom of the Intensity Profile control window named Graph, Data, and Measurement. Switch from the default Graph tab to the Data tab. The number, X, and Y coordinates of every point of the profile is displayed there in a table. They can be exported using the Export button described below.

Some measurement actions can be performed within the graph. The results are written to the Measurement tab.

Graph View Splitting

This option is enabled when the Multiple Profiles option is selected.

No split

Displays one graph view for all profiles.

Split horizontally

Tiles horizontally the graph view.

Split vertically

Tiles vertically the graph view.

Defining the Profile(s)

One or more intensity profiles can be displayed together. A profile is defined by an arrow placed inside the image. There are the following profile modes:

Note

Context menu over the basic arrows allows you to reverse the arrow, switch it to full size or open the Profile Properties (see: View > Layers Properties > Profile Properties).

Free line(s)

The profile line can be resized by dragging its ends by mouse arbitrarily. It is always a straight line

Vertical line(s), Horizontal line(s)

In this mode, the profile line is always in a vertical or horizontal direction.

Polyline(s)

This mode enables you to draw a free-hand (curve) or a polyline profile line. The existing profile line disappears and the cursor changes. Draw a curve or define a polyline by placing node-points to the image by single clicks. A right click defines the last point and finishes drawing.

Perpendicular

This mode displays two straight mutually perpendicular profile lines composing a cross. The cross can be resized and rotated. The zero value of x-axis is in the centre of the cross.

Multiple Profiles

If you switch from the single-profile mode to the multi-profile mode, a copy of the current profile line is created. Additional profile lines can be added by the Add Profile Line command from the context menu. Multi-selection of profile lines can be made holding Ctrl - the selected profile lines are indicated by a framed number.

Resize and move operations are applied to the selected profile lines.

Channels/Lines Mode
Channels Mode (shows graph lines in channel colors)

Graph lines use color of the original channel.

Lines Mode (shows graph lines in profile line colors)

Synchronize profile lines on multiple images

If working with multiple images, the profile lines can be moved in sync using just one of the arrows.

Shift Left, Shift Right

Shifts the intensity profile graph left or right by the amount of pixels specified in the edit box.

Zooming

The intensity profile graph may be zoomed in the usual way. You can click the zoom buttons placed on the control window sides (please see the Image Window chapter for the buttons description) or a mouse wheel can be used:

Opens the Distance Measurement panel. Please see View > Analysis Controls > Distance Measurement .

Measure > Options

The following window appears:

Rules for Excluding Objects

This section regards automatic measurement. Select the options how to treat the objects touching the area borders when you are performing the automatic measurement:

When using measurement frame

Pick up the option how to treat the object touching the measurement frame. Run the automatic measurement by the Measure > Use Measurement Frame command.

When using ROI

Pick up the option how to treat the object touching the ROI frame. Run the automatic measurement by the View > Layers > Measurement ROI command.

Without Measurement Frame and ROI

Pick up the option how to treat the object touching the image border. Turn off the measurement frame and ROI and run the automatic measurement.

Note

Rules for excluding objects are valid for all features of objects measurements. For field, frame and ROI measurement, these rules are taken into account only for the number of objects and do not affect the field measurement results. Field measurement is always applied inside the defined area without exceptions.

Object Colors

After the automatic measurement is performed, all measured objects are highlighted by color borders. Here you can select colors for the objects excluded from measurement according to the ROI/measurement frame settings. The Out of limits color will be used to highlight objects which do not fit the applied restrictions (View > Analysis Controls > Automated Measurement ).

Manual Measurement
Automatically zoom in Length manual measurements

This option zooms the image while placing the measurement points to the image. Only the indicated measurement tools are affected.

Copy manual measurement objects from live image to captured

If enabled, measurement objects made in the live image are copied into the captured image after the Acquire > Capture command is executed.

Label

The manual measurement objects can be labeled. Select what information will be attached to every manual measurement object in an image.
