Abstract
A method for super resolution enhancement of infrared imaging data employing an image array having simultaneous, high speed, randomly addressable windows of pixels for small regions of interest (ROI) within a large imaging sensor field of view. Data is retrieved from the ROI window pixels at an increased data rate and the array is dithered to produce sub-pixel motion consistent with the increased data rate. A selected super resolution (SR) algorithm is then applied to the data retrieved from the ROT window pixels at the increased data rate. The reduced data set substantially relieves the computational load on the processor compared with the requirement of performing SR processing on the entire frame of image data. The output from the SR algorithm is either used to replace the LR frame data in the image or is displayed as a separate image to the user.
