Enhanced vision technologies could be used to help the military pinpoint potential targets, aid pilots flying in bad weather and improve the accuracy of aircraft inspections.

Indian technology giant HCL recently revealed its suite of visual processing tech, including this satellite image processing technology, used to clean up images of the earth from orbit and bring them into sharper focus.

Here is the image after processing, shown on top, and before processing, below.

The cleaner image allows far more useful information to be extracted from the satellite feed, in this instance the categorisation of the various types of commercial, industrial, residential and other land in the shot.

The clearer satellite image is produced by bringing together high and low resolution images and by putting the images through a series of filters and other processes.
