摘要
本文给出了一种新近发展起来的多尺度几何分析框架下,基于方向信息的嵌入式图像压缩算法。该方法从图像本质的分析入手,提出了基于方向信息的稀疏表示图像压缩框架,充分考虑了视觉特性,提出了结合方向信息的嵌入式图像压缩编码方案。该算法不仅对图像的细节处理具有很好的效果,而且计算灵活方便,能得到较好的大压缩比效果。
Based on the new developed multi-scale geometric analysis （MGA）, a new algorithm for embedded image compression based on directional information is proposed in the paper. This new algorithm give us sparse coding frame based on directional information by image analysis in nature, and the human visual system is taken into account sufficiently in the compression algorithm. The proposed method has the improved accuracy and coding performance in image details, and this new algorithm can achieve high compression rate.
