Example of neutral line identification in one IMaX/SUNRISE magnetogram. The left column corresponds to restored and the right column to non-restored magnetograms (but they represent the same observations). The top row displays the original magnetograms, the bottom row overlays the neutral lines (blue contours) identified by the edge-enhancement procedure explained in the text. Note the increased frequency of neutral lines occurrences in the restored data.
