Subpixel registration for a high resolution imaging scheme using multiple imagers

In order to obtain high-resolution pictures at sufficiently high SNR, the authors have been investigating a signal-processing-based method that utilizes multiple low-resolution imagers and reconstructs a high-resolution signal by processing the low-resolution images. The method consists of registration of multiple images and reconstruction of high-resolution images. In the present work, the authors discuss an image registration scheme that exploits camera projection parameters so that the precision is substantially improved and the computational complexity is reduced.<>
