Repairing Artifacts and Cosmetic Defects
Cosmetic repair tools are used to correct blemishes and other artifacts in images. Use the commands below to repair the following types of defects:
Isolated hot or cold pixels: Create Pixel Mask, Apply Pixel Mask, Interactive Repair.
Residual hot or cold pixels that are not corrected by removing the dark current: Create Pixel Mask, Apply Pixel Mask, Interactive Repair.
Hot columns and Cold Traps: Blemish Mask Editor, Apply Blemish Mask.
Defect clusters larger than 1 pixel in area: Blemish Mask Editor, Apply Blemish Mask.
Cosmic rays and ionizing radiation events: Interactive Repair, Median Filter.
In addition, when several images exist of the same field of view, several methods may be used to reject artifacts and repair some of the larger cosmetic defects when the images are combined.
Apply Pixel Mask repairs isolated pixels using coordinates loaded from a file containing x,y positions of the bad pixels. Use this for repairing pixels that always are located at the same coordinates, such as hot or cold pixels.
Apply Blemish Mask repairs lines and rectangular regions of pixels that are always located at the same coordinates, such as hot columns, cold traps, and blemishes larger than 1 pixel in area.
Blemish Mask Editor creates and edits a blemish mask, which is a text-based description of blemish locations.
Create Pixel Mask is used to create a pixel mask by detecting isolated pixels that are very high or very low.
Interactive Repair Provides a pixel zapping tool used to repair pixels by interactively marking them on an image.
