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
