Abstract

To transmit an image over narrow bandwidth channels is an important issue in networks. We proposed a new progressive image transmission (PIT) method. We call it the fast reconstruction method (FRM). There are three techniques in this method. First, we use vector quantization (VQ) to compress the image. Then, we design the central sampling technique, and employ it to select the indices of the compressed image. These indices will be transmitted to the receiver phase by phase. Finally, the receiver applies the pixels copy technique and the received indices to reconstruct the image. From the experimental results, we see that FRM just needs 3.6% reconstruction time of the selective progressive image transmission method (SPITM) to reconstruct the image. Besides, the PSNR of our method is better than that of SPITM at the beginning phases. FRM is therefore effective and efficient in PIT
