Brightness balancing in images
Centre National d'Etudes Spatiales CNES - 10/17/2016
Description
Creation of a filter for correcting striping on images caused by local differences in sensor response. The level of correction to be performed is an iterative calculation comparing the brightness data across the neighbouring pixel columns. A correcting filter is then applied to the original image.
Benefits
Improving image quality - Brightness balancing in the nal image - Correcting the e ects of striping Economy of resources - Possibility of applying a set of prede ned parameters to correct similar images - No pre-calibration required
Innovations
Image-specific calibration - Auto-calibration of the image to process - Brightness assessment at pixel-level and at that of wider areas Universal image manipulation - Image processing independent of acquisition type - Requires no additional image or calibration
