JULIA图像与快速分形图像压缩编码

JULIA IMAGES AND FAST FRACTAL IMAGE COMPRESSION CODING

  • 摘要: 首先,本文根据统计规律建立一个小型固定字典,用以加速分形图像的压缩编码;然后,利用逃逸方法生成Julia图像算法生成8×;8的图像块,用作分形图像的压缩编码.因此,本文使用的压缩方法改变了由通常设计的分形图像压缩编码方法以变化的压缩编码字典进行编码的缺点.实验结果表明,本文所使用的方法能很好地对图像进行分形压缩编码,并具有分形图像的部分解码优点.

     

    Abstract: According to statistical law,this paper firstly creates a small fixed compression dictionary,which is applied to speeding up fractal image compression coding.Then,the paper creates a lot of 8×8 image blocks that use the escaping method to produce Julia images,which applies the image blocks to fractal image compression coding.For this reason,the compression algorithm in this paper corrects the defect of using variable fractal compression dictionary that was designed by Barnsley to realize fractal image compression coding.The experimental results show that the algorithm in this paper can realize fractal image coding very well and has some fractal image merit decoding.
