| Description:The Brightness_Correction class describes brightness corrections that were applied to an image or mosaic. Brightness correction is the process of adjusting the DN values of adjacent frames in a mosaic so they match visually. It may also involve contrast or vignetting adjustments. The result may no longer be radiometrically calibrated due to the adjustments. The processing_algorithm child of Brightness_Correction describes the type of brightness correction, and should correspond to the classes within Brightness_Correction_Image. If the algorithm is "MIXED", multiple algorithms were used, in which case the specific information in each Brightness_Correction_Image must be used. |
