Hongxing Cao · Dianzi qijian · 2009
An automatic image mosaic algorithm based on corner feature is proposed.First we analyze the principle and disadvantage of the Harris corner detection,based on this,an improved Harris corner detection algorithm is proposed to extract feature points,which reduced the amount of calculation,and improved the positioning accuracy,enhanced the capability of anti-noise.The transforming matrix H is computed with PERANSAC algorithm.LM algorithm is used to purify the transforming matrix H.Finally,image mosaic is completed with smoothing algorithm.The result shows that the accuracy of registration is improved greatly with this algorithm.It is high valuable in practice.
