An investigation of spatio-temporal deinterlacing methods on symbology overlaid thermal videos

In helmet mounted cueing systems (HMCS), the video displayed on miniature display is projected to pilots visor via optical components. It is necessary to convert interlaced videos coming from sources on platform to progressive ones before the other image processing steps. As far as total system latency is concerned, this process should be real-time such that it will not cause much delay. In this study, spatio-temporal methods using a few interlaced frames are applied on symbology overlaid thermal videos, compared and implemented on Field Programmable Gate Array (FPGA).
