A Fast Wavelet-Based Image Progressive Transmission Method Based on Vector Quantization

In this paper, we propose a fast progressive image transmission method based on wavelet decomposition and vector quantization. The wavelet decomposition provides the useful classified characteristic. In addition, vector quantization (VQ) has the advantages of high compression ratio and coding easiness. Combining these techniques, we further design different VQ coding strategies for the wavelet coefficients in different sub bands so that a fast and efficient progressive transmission can be provided. Experimental results also confirm the high PSNR and low bit rate can be achieved in the first two and three phases. Moreover, our proposed method has higher PSNR values and lower bit rates than BMP in the first two transmission phases which means our method is capable of helping the receiver to make an early decision as to stop the transmission session or not
