Claim 10:
11. A method comprising:
obtaining captured images of a moving target over a time period at a specified rate;
upsampling the captured images using interpolation of image data in the captured images to produce upsampled images of the moving target, the upsampled images having a higher resolution than the captured images, wherein the image data varies among the captured images due to movement of the moving target over the time period;
performing subpixel correlation using the upsampled images to produce aligned upsampled images of the moving target;
combining the aligned upsampled images to generate super-resolution images of the moving target;
identifying multiple edges of the moving target using the super-resolution images;
identifying an aimpoint on the moving target based on the identified edges of the moving target; and
updating the aimpoint on the moving target as the moving target moves over time;
wherein identifying the multiple edges of the moving target comprises using histogram binning and identifying at least one median edge location in morphologically-filtered imagery produced using the super-resolution images; and
wherein combining the aligned upsampled images comprises:
combining multiple initial aligned upsampled images to produce a high-resolution reference image;
registering additional aligned upsampled images to the high-resolution reference image; and
updating the high-resolution reference image with the registered additional aligned upsampled images while applying recursive weighting factors to older aligned upsampled images in order to forget the older aligned upsampled images over time.
