In this paper a method of image merge on micrograph is given

which introduces the template matching technique into image merge. Other problems occurred in the new application is also discussed. such as relative position nice adjustment of image. Template matching is more simple and effective than other methods of image merge fot that image which has no or small transform. Filter matching is one method of template matching. Since we don't know the noise function of the filter matching model in most cases

we hardly to use it directly. We do some pre process to make it work. Our method of image merge consists of three steps:template selection

template matching

and image align. To reduce the influence of noise we select the template on the basis of image segmentation. After template matching

both images are in alignment by rotating one image with an appropriate angle obtained from a multi resolution searching. The experimental result shows that our method is effective

simple and easy to use for micrograph merging.
