摘要
主要研究重构算法的贪婪算法中的正交匹配追踪算法,并提出了基于正交匹配追踪算法的改进算法,对图像进行列变换后,再对原图像进行行变换,然后综合两幅图像的优点,重构出原图像。仿真结果表明这种改进的算法能够有效地提高重构效果。
In the paper, an orthogonal matching pursuit （OMP） algorithm is studied, and then an improved signal recovery algorithm based on OMP is presented. First, it transforms the original image in the column, and then transforms the original image in the row. The original image is reconstructed out by synthesizing the advantages of two images. Simulation results show that the method can efficiently improve the reconstruction performance.
