Restorer is a visualization technique for indicating the location of missing data in a scientific visualization. Rather than filling missing data regions with interpolated data colored with the same scale as real data or simply leaving such regions empty, the restorer technique fills the regions with interpolated data colored with a color table with only luminance values. This technique allows missing data to be indicated clearly without distracting from the content of the real data. Note: A narrated video describing the restorer technique and giving several examples.
