The Erase grid lines, cage bars or cables window

In brief

You can use the options in this window to erase grid lines, cage bars, cables, wires, tubes, etc. from the video image.

Details

To erase lines that are darker than the background of the image, you should first select the First...Erase dark coloured grid lines or cage bars button and then adjust the Intensity slider until the lines just disappear. Surprisingly, this may cause light coloured lines to appear in their place; if this occurs, then select the Second...Erase light coloured grid lines or cage bars button and then adjust the Intensity slider until the pale lines just disappear too.

If the lines are lighter than the background of the image, you should simply reverse the above process; i.e. first erase light coloured lines and then, if necessary, erase any dark lines that appear.

Take care not to use an unnecessarily high intensity; this will simply reduce the image quality.

Although ANY-maze will erase lines in the images it uses internally to track the animal, the image you see on the screen will be the unadjusted image, and will continue to have the lines shown. The only exception is when you're using this window to actually set the erase parameters.

Special considerations when using montage video sources

As you may know a montage video source shows images from two other video sources joined together. Usually, any adjustments you make to the constituent sources will appear in the montage source, but erasing lines is an exception.

You can use this function in any constituent video source, but the image used by the montage source won't have the lines erased. To erase them in a montage source, you should select the montage source and then erase them there - see figure 1.

Figure 1. A montage source uses the images from the constituent sources before any lines are erased in them. Therefore to erase lines in a montage source, you must apply the erasing to the montage source itself.
