Importance and effect of co-registration quality in an example of “ pixel to pixel ” fusion process

Résumé

By definition, as they require the images to merge to be superimposable, « pixel to pixel » fusion processes raise up the issue of the outcome of geometric co-registration quality on the resulting images. Indeed, local errors of geometric co-registration may introduce local errors in the merging process. Hence, we can wonder how can we define and reach the co-registration quality level that is required to minimise errors in « pixel to pixel » merging processes. The aim of this work is to understand, thanks to an example of such fusion process applied to images with different degrees of geometric distortions, the outcome of co-registration error on the fusion quality and, therefore, to measure the efficiency of some co-registration methods for the pre-processing of « pixel to pixel » merging application.
