Classification: CPC F  G | IPC G  H

Claim 0:
1. A system comprising:
at least one imaging sensor configured to capture images of a moving target over a time period at a specified rate; and
at least one controller configured to:
upsample 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;
perform subpixel correlation using the upsampled images to produce aligned upsampled images of the moving target;
combine the aligned upsampled images to generate super-resolution images of the moving target;
identify multiple edges of the moving target using the super-resolution images;
identify an aimpoint on the moving target based on the identified edges of the moving target; and
update the aimpoint on the moving target as the moving target moves over time;

wherein, to identify the multiple edges of the moving target, the at least one controller is configured to use histogram binning and identify at least one median edge location in morphologically-filtered imagery produced using the super-resolution images; and
wherein, to combine the aligned upsampled images, the at least one controller is configured to:
combine multiple initial aligned upsampled images to produce a high-resolution reference image;
register additional aligned upsampled images to the high-resolution reference image; and
update 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.
