摘要：Image matching is an important task. The matching problem is also known as correspondence problem. In an image, matching can be defined as the establishment of the correspondence between various data sets. Many steps of the photogram metric processing chain are linked to matching in one way or another. In this paper we proposed a method direct matching for gray scale image. Template image is directly mapped with reference image i.e each corresponding pixel is subtracted from the reference image and saved as difference then sum is compared with Tolerance value and then the minimum value of the sum is taken. Then the coordinates of x and y are saved where the image is matched.a
