Abstract:

According to the analysis of radiometric equalization,moment matching and histogram matching,an effective method for removing the stripe noise in CBERS-02 data is developed.The main idea of this method is,first of all,using histogram matching to remove the stripe noise along-track on the image,then applying linear directional filtering to remove the residual stripe noise along-track and across-track in the image.Results of CBERS-02 data showed that the proposed algorithm reduced stripe noises without degrading image quality.To evaluate performance of the proposed method,quantitative and qualitative analyses were carried out by visual inspection and quality indexes of destriped images.
