A new detecting algorithm for close region, which has rectangle or parallelogram shape (e.g. airfield track), is developed in this paper. The traditional detecting algorithms for this kind of close region have some faults: long operating time and high demand for image quality. Mainly based on gray level shifting characteristic and size characteristic of close region, this proposed detecting algorithm for close region is not needed to extract line and search parallel lines. In this algorithm, a new terminology-edge dot couple, which is used as parameter of close region detection, is expressed and the method to extract it is described. A new technology-region growing, which use edge dot couple as growing base, is developed to search out close region. The author applies this algorithm to detect airfield track. The experiment result shows that this method is good for the close region detection.
