一种自适应分块图像压缩算法的研究

自适应分块图像压缩是存四叉树分解图像压缩原理批础上研究设计的一种新的算法。将图像中像素值相同的相邻像素点尽可能划分到同一个图像块中，采用稀疏矩阵三元组存储方式对图像块参数进行存储，从而达到图像爪缩的目的。使用MATLAB对算法进行了仿真，成功地完成了图像压缩和重建，并在不同条件下，对图像压缩过程中的各个参数与四又树分解进行了分析比较。结果表明新方法分块自适应度高，提高了图像压缩比。

Research on a image compression arithmetic of auto-adaptive blocking

The auto-adaptive blocking image compression is a new arithmetic designed and proposed on the basis of the theory of the quad tree decomposition. It partitions the pixels of the same value to a same image block as much as possible, and the parameters of each image blocks are stored in three vectors using the sparse matrix storage mode, achieved the purpose of data compression. The new arithmetic is simulated on the MATLAB processing platform, and the compression and rebuilding of the image are completed. In...
