Scene Matching Algorithm Based on Similarity SecondOrder Difference

  • An algorithm was presented, in which the minimum of second-order difference of similarity surface was adopted as the criteria of the selec tion of scene matching points, on the basis of analyzing the characteristics of scene matching similarity surface. The trustability of the matching point can be further determined by means of above criteria. The experimental results show th at this algorithm is effective in improving the matching probability compared wi th the traditional methods, for example the ma tching probability improves from 92.7% to 98.1% in this experiment. The confiden ce levels give a good representation of the matching point evaluation, and can b e used as a kind of reference standard for eliminating of mismatching points.
