Abstract

Super-resolution reconstruction algorithms have been demonstrated to be very effective in enhancing image spatial resolution by combining several low-resolution images to yield a single high-resolution image. However, the high computational complexity has become a major obstacle for the use of super-resolution techniques in real time applications. Most previous computationally efficient super-resolution techniques have been focused on reducing the number of iterations due to the iterative nature of most super-resolution algorithms. In this paper, we propose a region-of-interest (ROI) image preprocessing technique to improve the processing speed of super-resolution reconstruction. To better integrate the preprocessing with super-resolution, the proposed ROI extraction technique is developed under the same statistical framework as super-resolution. Simulation results are provided to demonstrate the performance of the proposed method.
