An Improved Algorithm of Radon Transform Based on Gray Constraint Accessional Strategy

A new algorithm based on gray constraint accessional strategy is presented.We discuss the information of runway endpoints that the bomb dispenser need and give the prior knowledge of the gray constraints for the airfield targets in infrared image.Compared with the traditional Radon transform algorithm,the proposed algorithm is more effective to obtain the information of the midpoint and the endpoints of the runway.Experimental results demonstrate its effectiveness.
