Traditional ghost image (GI) relies on the intensity fluctuation correlation between the reference beam and the object beam. In this paper, a novel analysis for characteristic recognition ghost imaging (CRGI) is proposed based on characteristic classification of the light field, which indicates that GI can be considered as the superposition of ghost images with different characteristic information. The analytical results show that the reconstructed images of GI by processing the reference light are identical to that by processing the object light, which make it possible to utilize the prefabricated reference light to recognize the target characteristic in the imaging process. Moreover, the distinction between targets can be clearly identified by CRGI when the difference of characteristic information is quite slight, while it is difficult to be distinguished in traditional GI. Our results not only provide a new method for real-time characteristic recognition, but also promote the development of GI technology in fields such as medical imaging and security systems.
