Melhoria do processo de correçâo geométrica de imagens CBERS-CCD pelo uso de amostras georreferenciadas classificadas

Abstract

The CBERS satellite images are freely distributed, but a geometric correction method is required to allow their use. We propose improvements over the automatic correction method by selecting the best reference samples from which control-points are generated. Further, those tie points will be used to define the geometric model used on the correction process. To demonstrate the effectiveness and performance gain we applied the correction method to a set of selected CBERS images using the automatically selected samples.
