- W2383286222 abstract "At the case of not increasing the focal length of the optical system,and not narrowing the array element width of CCD devices,in order to reconstruct super-resolution images,researched multi-frames of under-sampled low-resolution images with the complementary information.First,they transformed multi-frames of under-sampled low-resolution images with the complementary information to the frequency domain by the Fourier transformation.Secondly,in the frequency domain,modeled the relationship between super-resolution image and the low-resolution images,which could get the relationship between them.Thirdly,acquired the frequency values of super-resolution images by solving the model.Finally,got super-resolution images from the frequency values of super-resolution image by the Fourier inverse transformation.The experimental results show that: this reconstruction method can obtain much more clearly super-resolution image in the visual than the recovered super-resolution image through the bilinear interpolation to an arbitrary low-resolution image,almost achieve the same with the actual intake of one times high super-resolution image.PSNR of the restoration of the bridge image can be achieved 34.767 3 dB.Computer simulations demonstrate the performance of the algorithm.So this method is practicable,and the restored image has good edge visual effects." @default.
