| Abstract: | By new theory of compression sensing,realizes compressing gray image at a lower sampling rate through Harr sparse orthogonal transformation and Bonuli observation matrix,and restores compressed data by algorithm of orthogonal match pursuit.The experiments show that this method realizes compression sensing quite well. |

| Keywords: | Harr wavelet compression sensing sparse non-adaptive orthogonal match pursuit |
