Abstract: According to the traditional pixel-level image fusion method fragmented issue of linkage between pixels proposed，the image fusion method is put forward，which is based on the regional detection.First of all，through the pixels in its neighborhood of the variance，the way is used to distinguish whether it is clear point or ambiguous point.Secondly，to have a clear area by the current pixel as the center of the floating window，the corresponding window region，a clear statistical points，eliminating the center of fewer pixels clearly points to the same way local window region，a clear statistical points，points more clearly the center of pixels set to a clear point.Finally，according to the results of detection，regional images is integrated.Experimental results show that the proposed method is effective.
