Evaluation of Image Edge Detection Algorithms in Scene Match Positioning

Fourteen kinds of representative edge detection algorithms including classical and modern ones are studied,and the applications of these algorithms in scene match positioning are simulated.According to the actual combat requirements of tactical aircraft and cruise missile,some performances of these algorithms are presented,and the applicabilities and prospects of these algorithms in scene match positioning are explored.It has been shown by the simulation results that wavelets algorithm is the best one in positioning precision and matching probability,and its realtime ability is also good.Fuzzy and neural network algorithms should also be paid attention to due to their excellent performances.
