Image matching algorithm with high precision

A novel algorithm for image matching with high accuracy is proposed to achieve the requirement of spectrum restoration based on optical flow computation. This matching algorithm overcomes the defects of traditional image matching algorithm based on gray matching, which are affected by interpolation accuracy,and breaks the conflict between operation speed and accuracy. Experiments on real hyper -spectral image sequences show that our method is not only effective both in efficiency and accuracy, but also more suitable for the hardware realization compared with MAD block matching algorithm and normalized correlation coefficient block matching algorithm.
