“…Among the various forms of JTC-based target recognition, the fringe-adjusted JTC (FJTC) technique has demonstrated great enhancements in detecting the correlation output peaks 13 – 16 In practice, multiple target detection faces many challenges, such as target variations from the same class and between class similarity, orientation, scaling, noises, deformations, and occlusions. To alleviate some of these problems, several methods were reported, such as Fourier plane subtraction, shifted phase-encoded technique, and reference phase-encoded technique 14 , 15 …”
