Restoration for Damaged CCSDS Image by using Cross Band Information

Abstract

The CCSDS standard is a format for satellite remote sensing When the coded CCSDS image has been transmitted from space to ground the data can be damaged and distorted because of the long distance the signal has travelled Even a single bit error can cause significant damage after decoding and result in low availability for further applications A scheme is proposed to deal with such circumstance The FORMOSAT-2 satellite is capable of capturing multispectral images which are essential information for restoring the corrupted images Though the brightness of different band images may not be the same the structures of these images remain similar to each others A weighted modified mapping function is generated by the correlation between different band images to restore the damaged image The experimental results show that the proposed method is capable of reconstructing the error image with great visual quality
