Find Objects by Color

Main Menu: View > Find Objects
Toolbar button:

Bersoft Image Measurements uses a semi-automatic method to find isolated regions of a particular color in an image (see also: Find Objects Automatically).

The operation would be as follows:

  1. Open the image where you want to find the objects and use the Automatic Area measurement tool, to select either the objects you want to measure or the background surrounding them. In case you clicked on the background, select Invert .
    If you are selecting the objects instead the background clear Contiguous.
    If you select the background, unselect Contiguous and select Invert, in that way you will select the objects indirectly.
    The objects should be completely separated from each other. Take care of adjusting precisely the selected objects area before proceeding to the next step.

    In case objects overlap only slightly you can apply a Maximum (dilation) filter to separate them (click Ctrl-Alt-F or the Image > Filters menu and then select the Morph tab).
    Learn more about the Automatic Area measurement tool in order to be able to select precisely the objects.

  2. After the objects are correctly selected open the Find Objects window by clicking in the toolbar.
    Notice that
    Find Objects will not appear unless you previously selected an image area with the

  3. Optionally you can clear or add image areas to the selection, before finding the objects. To do so select the or in the Selection Settings Palette and click on the area you want to add or subtract from the selection..

  4. Click (see the image below). Both the selected objects and its numerical values will appear.

Click on any column header to sort the table on that column.

The columns, from left to right, are:

Object #

Objects are assigned consecutive numbers when they are found in the image, which is scanned from left to right and top to bottom.


Optionally adjusted by the Conversion factor.


 Xc and Yc are the center of the object coordinates.
Optionally adjusted by the Conversion factor.



Optionally adjusted by the Conversion factor.


% Shows the area percentage with relation to the sum of the total area in the same series, or in all series, depending on if  Calculate % for each series menu option is selected or not.


This column has no title and shows the color of the Series to which the object belongs.


The name of the Series to which the object belongs.

 Obj . Series #

If there is one single series, the Obj . Series # will be the same than the Object #.

The table values may be exported or copied to the clipboard. See The Menus below for more details.

By default the objects and the background are painted with the colors specified in the Tools Palette. If more than one series is used, each series will be assigned random different colors.
Optionally click to set objects series and colors. Learn more.

Use conversion factor




If selected, all values (area, coordinates, size, etc.) will be converted, by applying the conversion factor, if not they will be shown in pixels.
The intervals assigned to the series in the Edit Series window are affected by this option, because the conversion value will be applied also to them.

Include objects at edge of image



If this option is not selected, objects which touch any edge of the image will not be found.
Print General Object # on image



Objects are searched for from left to right and top to bottom and assigned sequential numbers. If this option is selected the object number will be printed on each object.

Print Series Object # on image



Instead printing the general object number the series object number will be printed.

Calculate % for each series



This options only works if more than one series is set by using the Edit Series window
If checked, each object percent will be relative to the series which it belong, otherwise, each percentage will be relative to the total area of all series.
