摘要 |
<p>In order to correct the swathe related banding effect often seen on swathe-scanned imagers a vertical smoothing function separates out artifact detail from the idealised image and derives from this, proportional corrections for each channel within a swathe. In cases where the artifact varies from swathe to swathe a second algorithm is used to obtain correction values for each line of the image.</p> |
