Progressive satellite image transmission based on integer discrete cosine transform

This study proposes a progressive transmission method for satellite images based on the integer discrete cosine transform. It has two characteristics, low-complexity and lossless reconstruction ability. Besides, high quality intermediate image can be obtained at the early stage with a low bit rate. The reconstructed images visual quality at stage 4 is acceptable and the associated bit rate is approximately 0.2. In addition, when all stages transmission completed, the reconstructed image is accurately recovered. Experimental results demonstrate the effectiveness of the proposed method and show it outperforms the classical low-complexity progressive transmission method based on BPM. Our method can be used in many practical applications of satellite image transmission.
