Packetization of the SPIHT-coded bitstream using an evolutionary-based optimization technique
Ezzatollah Salari, Jianming Wei · 2007
The problem of packetizing the SPIHT-coded image bitstream into fixed-size packets is investigated and an optimal packetization scheme using a genetic algorithm (GA) is presented. In the proposed method, each individual packetization instance is represented by a decision sequence and mapped to a chromosome. A steady-state genetic algorithm is applied to search for the optimal chromosome that minimizes the distortion between the original and the reconstructed image data. The computer simulation results show that our proposed packetization scheme has high compression efficiency and provides error resiliency to packet losses with a relatively fast speed.
