with real time candidate handling and precision space craft control fuego has the capability of taking multiple images where each image is shifted by a small fraction of a pixel and then measuring and analyzing the behavior of the candidate at slightly different pointings the fuego camera would be moved by a fraction of a pixel and a new image would be acquired this could rule out slower spreading fires other algorithms may be useful such as subtracting a smoothed version smoothing over for example an extent of 4 u00d7 4 pixels of the new image from itself the u201c treated new image u201d and then a smoothed image of the reference image from the reference images the u201c treated reference image u201d and then subtracting the treated reference image from the treated new image this method tends to eliminate noise due to low frequency changes in the background illumination finally if necessary the use of a ground system of lasers without limitation ir in bandwidths of interest could point at the satellite since the satellite telescope has no moving parts thereby allowing images to be precisely aligned over successive pointings by collocating the lasers mid wave ir 4 05 u03bcm images from the.
