摘要
针对东巴经典古籍的历史特征以及图像化象形文的书写形式,进行数字化图像信息处理时存在着压缩保存的问题,对获取的东巴经典古籍进行了图像压缩研究。首先利用分形理论对图像信息进行压缩处理,进而引入小波变换理论,将分形与小波相结合,再次利用图像信息的自相似性进行二次图像压缩。实验结果表明,该方法针对象形文字图像信息的压缩,具有压缩质量好、压缩比高、且压缩时间较短的效果。
Based on the historical characteristics of Dongba manuscripts and image of hieroglyphic writing,to deal with the problems in digitized image information processing,the image compression of Dongba manuscripts is researched in the paper. The image compression process is firstly studied by using fractal theory,and the theory of wavelet transform is introduced. The fractal and wavelet are combined to implement secondary image compression based on image information self-similarity. This method has the advantages of good compression quality, high compression ratio and short compression time for hieroglyphic image information compression.
