Manually Classifying Objects in an Image

Once you have done a Count/Size operation to identify objects in an image, Image-Pro allows you to select individual objects or groups of objects and “tag” them as part of one class or another.

To manually classify objects in this way:

Go to the Count/Size ribbon on the Image-Pro ribbon bar.

These instructions assume your image is already opened in the workspace and the objects have been counted.


In the Class group on the Count/Size ribbon, type a name in the text box for the first class of objects you want to tag, and use the color selector to assign it a color.

Click the Select tool in the Select group.

Click on the objects in your image that you want to assign to the first class.

Note that holding down the <Ctrl> key allows you to select multiple objects.

In the Class group, click on the Apply tool.

The selected objects are applied to the class.

Repeat steps 2-5 for each class of objects you want to manually tag in the image.

Information about your manually classified objects appears in the Data Table below your image.
