Our algorithm assumes that the misalignment between the two consecutive exposures is translational. Using a photographically guided random search, our algorithm first finds properly exposed high contrast regions. The shift amount is then found by analyzing and matching the pixel correlations inside these regions.Categories and Subject Descriptors: Image Processing and Computer Vision [I.4.3]: Enhancement-Registration
