Estimation of mutual subpixel shift between satellite images: software implementation




satellite imagery, subpixel shift, software implementation


The special-purpose software implementation for estimating the subpixel shift between satellite images using advanced computer technology is described in this paper. The automatic calculation of the mutual subpixel shift between a pair of digital satellite images by correlation algorithm is performed. The proposed implementation was tested on a statistically representative number of satellite images and reached acceptable accuracy in determining their subpixel shift values.
