Computational super-resolution and integral imaging in the the thermal infrared (long-wave band), using an array of 6x low cost compact cameras (FLIR Lepton).

Digital refocus example with simultaneous enhancement of native camera resolution by applying integral imaging and computational super-resolution in a 6x thermal camera array. <br>In the first item we show an example of digital refocus with enhanced native resolution in a static scene, showing a comparison of the original low-resolution image from one of the cameras (left), and the computed high-resolution image (right) at different digital refocusing distances.<br>In the second item, we show a similar example but operating at video rate, where the low resolution video sequence(top-left) is compared to the processed high resolution video digitally refocused at 3 meters and 6 meters (low-left and right, respectively), and also to video with a variable digital focus distance between 3 meters and 6 meters (top-left).
