Improved target detection and recognition in complicatedbackground with joint transform correlator

摘要

We present an effective method to enhance target detection and recognition by Canny algorithm, whichcan obtain the continuous and distinct image edges, also suppress back-ground noise effectively, for thisreason, correlation output processed by our proposed method provides higher discrimination than theclassical JTC. Computer simulations demonstrate the improved method can obviously suppress noise andsidelobes, also enhance the performance of detection and recognition for JTC. An optoelectronic hybridJTC is constructed to verify the efficiency. Experimental results present the sharp correlation peak andalso confirm the method effectiveness.Crown Copyright
