摘要	A super-resolution technology of combining hardware and software was researched. Firstly, the detector scanning was used to obtain multiple images with the same scene produced by different motion parameters and they were chosen to be training sets and input images. In consideration of that traditional Local Linear Embedding (LLE) super-resolution technology is over-relying on external training images and is inconvenient for processing image directly, a improved self-learning algorithm based on the LLE was proposed. The new LLE weight calculation method was proposed to obtain initial estimation of HR image. Meanwhile, self-learning LLE algorithm was used to recover lost high-frequency information of initial estimation and to obtain the final estimation. Simulation results show that the Peak Signal to Noise Radio (PSNR) of the reconstructed image by proposed algorithm improves 0.8 dB and operation time shortens by 75% as compared with those of conventional LLE method, respectively. Moreover, in the real scene experiment of micro-displacement platform, the Signal to Noise Radio (SNR) and information entropy of the reconstructed image by proposed algorithm have also greatly improved as compared with those of other algorithms. The algorithm provides high quality reconstruction image and improves the resolution of the captured image. , 2015, Chinese Academy of Sciences. All right reserved.
