Student thesis: Master's Thesis


The Consultative Committee for Space Data Systems (CCSDS) proposed an image compression standard (CCSDS-ICS) which can do the efficient and lossless compression and is most widely utilized for the satellite communications so far However the original CCSDS-ICS is weak in the ability of error resilience that severe error propagation would be caused by even an incorrect bit in the compressed file In this thesis the bit-error-caused damages in the images are going to be concealed The Neighborhood Similar Pixel Interpolator (NSPI) was originally developed to fill the gaps owing to the failed Landsat 7 ETM+ Scan Line Corrector (SLC-off) To make it work well on the large contaminated areas in the satellite images an adaptive searching window is proposed to improve the way of the NSPI method to acquire the similar pixels Furthermore an automated system is designed to do the image rectification error detection and error concealment for the bit-error-caused damages in the images The results show that the proposed algorithm can reduce the processing time to restore and obtain better visual quality of the restored images
