摘要
提出基于归一化的条纹调制联合变换相关识别方法(FAF NJTC),分析证明了这一方法的可行性.数值模拟结果表明,新方法的相关输出结果与NJTC相比相关峰更加明显、锐利,与FAF JTC相比则大大地提高了其抗干扰的能力,且不同光照下的相关输出稳定;0~0.2噪声级的计算表明,新方法较大地提高了相关结果的平均强度之比(PBR)和分辨率.
Abstract
In this paper, a new method for target recognition, normalized fringe-adjusted joint transform correlation is proposed. Analysis shows that the method can work more effectively. Simulation results show that, compared with NJTC and JTC, the correlation peak is more obvious, sharper; compared with FAF JTC, the anti-noise ability is greatly increased; and simulation shows that in 0 to 0.2 noise level, the new method increases PBR, and discrimination; the output is stable under different illumination.
