This step in the Image Analysis Wizard enables you to add or remove individual objects to be measured. The step can be considered a manual "fine-tuning" of the automatic detection results of the previous steps. After this step, all the objects you wish to measure should be selected and any you do not wish to be measured should be removed.

All the objects detected with the current settings are highlighted in the image.

If you need to make large numbers of manual corrections, it might be quicker to try adjusting the parameters in the previous steps first.

  1. If you wish this step to be included when the job is run, activate Interactive.
  2. Otherwise the step is skipped.
  3. Select the class for which you wish to modify the settings.
  4. You can specify different settings for each class.
  5. To add a new object or remove part an object, click Draw or Erase and use a drawing tool in the image.
  6. Draw: Adds the area drawn as a new object
  7. Erase: Removes the area drawn from any existing objects; the remaining parts of the objects are measured
  8. For more information about how to use the drawing tools, see Interactive Segmentation.
  9. To split an existing object into multiple objects click Cut and draw a line in the image where the object should be split.
  10. The resulting objects are measured separately.
  11. To extend the size of an object click Merge and use a drawing tool in the image.
  12. If the area drawn overlaps an existing object, the area and object are joined into a single object.
  13. To fill an object containing a hole, click Fill then click an object in the image.
  14. The hole is filled and the complete object is measured.
  15. To delete objects, click the desired action and then click an object in the image:
  16. Remove: Deletes the selected object; the object is no longer measured
  17. : Removes all objects; no objects are measured
  18. To expand or reduce the size of an object based on the brightness of surrounding pixels, click + or - and click a representative area in the image. The amount by which the object expands or reduces depends on the brightness of the selected pixel, its proximity to other objects, and the values of the Intensity and Color parameters.
  19. +: Expands the closest object
  20. -: Reduces the closest object
  21. Click Next.
