In a general, different sensor images of the same scene have different gray characteristics, Simple algorithms such as t hose based on area comelation can not be used directly. Therefore, an edge feature-matching algorithm is pressed in this paper. The algorithm uses feature parameters of edges as matching primitives. An edge deleetion approach with wavelet is discussed in order to extract edges form images. The mathematical models of edge representation and matchin algorithm based on line moments are developed. Results obtained from above metbods are reported.
