摘要:
通过对图像进行不平等保护来改善图像的质量和清晰度.先对图像进行小波变换,提取出其低频和高频数据信息,并依据重要性的不同,对提取出的数据信息进行划分,然后联合Turbo码对划分后的图像数据信息进行不平等保护.通过仿真数据看出本文的方案使图像的质量得到改善.
Abstract:
In this paper.we extract the low and high frequency data information of the image and divide thedata information according to their importance based on wavelet transform.Then we use the unequal error pro-tection scheme combined with the Turbo codes to protect the image data. And the results show the scheme weproposed can improve the quality of the image.
