Abstract

The problem of scene matching is a challenging problem in the field of image processing and pattern recognition. Given a pictorial description of a region of a scene, it is desired to determine which region in another scene is similar. The simplest method to solve this problem is called "template matching" and suffers from the great amount of computations required.
The most efficient algorithms for scene matching are discussed.Those are the sequential hierarchical scene matching algorithms for gray-scale and binary images and the two-stage template matching algorithm. Experimental results are presented for matching satellite images of Al-Minea (EGYPT) and Montana (USA) using those approaches. The experimental work is done using the Remote Image Processing System , Military Technical College. The results prove efficiency and success in reaching the best match location with minimum required computations. A comment on the results is presented as well as a comparison between the applied methods.
