Add Marks by Traversal


The traversal feature (see Traverse Marks) provides an efficient way to mark images. Users can mark one image and then use the mark traversal feature to mark a second image.

You may traverse the select marks either "By point creation order" or "From left to right". The former refers to the order in which you marked the image. This method may be convenient if you marked the reference image systematically. The "From left to right" method starts from the top left corner of the reference image and moves across to the right. It then skips to the next line and proceeds to the end.

The following steps explain how to perform mark traversal:

  1. Mark some feature points in image P.
  2. Set image P as the reference image in the Mark page of the Main window.
  3. Select some or all the marks in image P, and select either the "By point creation order" option button or "From left to right" button.
  4. Press "Start" to begin traversing. One selected mark will become the current point.
  5. If the point can be seen in a second image, Q, click the right button at that point. This will add a mark in image Q to the current point.
  6. After adding a mark in image Q, the current point will automatically move to the next selected mark in image P. Repeat step 4 to add marks in image Q for all the corresponding points in image P. If a point in image P does not appear in image Q, press "Next" button in Main win- dow to skip it.
You can mark all the point in one image, then mark the other image using the traversal feature. After marking all the images, you can then use the traversal feature to check the correctness of marking.
