A method of enhancing the output of low resolution thermal sensors is investigated. Current thermal imaging arrays are limited in pixel count with a large pixel size, resulting in output images of relatively poor quality when compared with consumer camera modules in the visible spectrum. Due to physical limitations this is likely to remain true for several years to come. Utilising small shifts in the thermal channel, an enhanced output can be obtained that allows for a resizing of input images with no apparent loss in detail.
Simulation and theory are presented, together with some initial results.
