Paper Abstract

We propose an image registration technique to be implemented on mobile devices equipped with cameras. We address the limited computational power and low-quality optics of such devices and aim at designing a registration algorithm, which is fast, robust with respect to noise, and allows for corrections of optical distortions. We favor a feature-based approach, consisting of feature extraction, feature filtering, feature matching, and transformation estimation. In our application, the transformation estimation is robust to local distortions, and is accurate enough to allow for a subsequent super-resolution on the registered images. The performance of the technique is demonstrated in fixed-point implementation on the TMS 320 C5510 DSP.
