[0128] 1, emulation condition: the emulation of the present invention is at windows 7, SPI, CPU Intel (R) Core (TM) i5-3470, basic frequency 3.20GHz, software platform is to run on Matlab R2011b, what emulation selects is four frames of 512 * 512 Standard test natural images Lena, Barbara, Boat, block size.
[0129] 2. Simulation content and results:
[0130] Simulation 1:
[0131] Under the condition that the sampling rate is 20%, the Lena image is reconstructed respectively with the method of the present invention and the orthogonal matching pursuit method (OMP) under random Gaussian observation, and the simulation results are shown in Fig. image 3 shown, where image 3 (a) is the original image of Lena, image 3 (b) for image 3 Partial enlarged view of (a), image 3 (c) is the reconstructed image obtained by the orthogonal matching pursuit algorithm (OMP) under random Gaussian observations, image 3 (d) for image 3 Partial enlarged view of (c), image 3 (e) is th...
