Abstract

The stereo image pair taken from different positions, theoretically the redundant information and disparity allows to reconstruction higher resolution images and reduces the aliasing artifacts. We present an improved hybrid MAP (Maximum a Posteriori) restoration algorithm for stereo image pair combined PSF (Point Spread Function) measurement and iterative registration parameters updated scheme. With the regularity parameter choice based on L-curve, this method preserves discontinuity efficiently. The reconstruction images quality lies on the accurate registration, the PSF non-bias estimation and regulation parameters choice. In this paper, an MTF (Modulation Transfer Function) measure and spatial profile methods are presented for reconstruction images quality estimation. A simulation and a real-data experiment demonstrate the performance of the algorithm.
