This filter sharpens any fine image details that are of low contrast. It determines the contrast of a region by calculating a ratio between the average value in the neighborhood and the standard deviation of the same neighborhood. The difference between the pixel and the average background is then multiplied by this contrast factor. Thus, variations in areas of low contrast are preferentially amplified. This algorithm can be very effective for extracting subtle details from planetary images; however, it can also cause excessive noise amplification so it should be used with care.
Radius controls the region that is considered ”local”. Smaller regions result in more amplification of smaller details, but also tend to amplify noise more. Contrast (%) determines how much of the contrast amplification is applied.
Availability of this feature depends on Product Level.
