Personalized shadow puppet face generation method based on constraint generative adversarial network

The invention discloses a personalized shadow puppet face generation method based on a constraint generative adversarial network, and the method comprises the steps: building a generative adversarial network which is used for converting a real face image into a shadow puppet face image, and introducing a local geometric feature constraint function into the generative adversarial network, calculating an image domain required by loss generation through a local geometric feature constraint function, and obtaining a generative adversarial network model meeting requirements by constraining geometric deformation of typical facial features in a training process of the generative adversarial network; and inputting a real face image into a generator of the generative adversarial network model, and generating a shadow puppet face image of which part of features are consistent with the real face. According to the method, the defect that the shadow puppet face generated due to texture loss and geometric structure transfo
