基于通道编码的数字图像恢复算法
|
摘要
信息损失不可避免。为达到图像的篡改容忍度与恢复质量之间的平衡,基于纠错编码方法,对原始图像采用SPIHT编码进行整体压缩,再用RS纠错编码对SPIHT源码流进行保护,将编码后的RS码流作为水印嵌入宿主图像。实验结果表明,该算法的图像质量和篡改容忍度均有所提高。基于纠错编码的图像恢复技术能够保证在篡改容忍度以内恢复所有的压缩码流,大大降低接收端解压的计算复杂度,提高图像恢复效率。
In order to achieve a balance between tolerance of tampering and restoration quality of image against endless information loss,this paper uses the method of error correction coding to compress the original image by SPIHT and protect the SPIHT out-stream by RS technology,and the RS stream is embedded into host image as watermark.Experimental results show that the quality of the restored image and the tolerance of tampering are improved.The image restoration technology based on error correction coding can guarantee the recovery of all compressed code streams within the tamper tolerance,and it can greatly reduce the computational complexity of the receiver decompression and improve the efficiency of image recovery.
