Abstract

The embodiment of the invention discloses a training method, device and equipment of an image generator and a storage medium, and relates to the technical field of artificial intelligence such as deeplearning, big data processing, data enhancement and computer vision. The method comprises the following steps: respectively inputting codes of a first modal image and a second modal image of the sameobject into an initial model of an image generator to obtain a first image and a second image; respectively inputting the first image and the second image into a target network model to obtain a feature value of the first image and a feature value of the second image; and determining a loss function based on the feature value of the first image, the feature value of the second image and the typeof the target network model, and adjusting the parameters of the image generator to obtain a trained image generator, thereby providing an image generator capable of generating a specific modal imagein the first modal image and / or the second modal image. The problem of overfitting caused by too few training samples of a specific modal image recognition model is solved, and the recognition precision of the model is improved.

Description

technical field [0001] This application relates to the field of computer technology, specifically to the field of artificial intelligence technology such as deep learning, big data processing, data enhancement, computer vision, etc., especially to the training method, device, equipment and storage medium of the image generator. Background technique [0002] At present, the widely used camera is RGB (color of three channels of red, green and blue) cameras, it is relatively easy to obtain face data in RGB mode, and the training data for face recognition model in RGB mode is sufficient. However, in addition to the RGB mode, there are more face data of other modalities, such as Depth (depth) and NIR (near infrared), etc., due to the great difficulty in cost or technology, the face data of other modalities is extremely difficult at present. few. Contents of the invention [0003] Embodiments of the present application provide a training method, device, device, and storage medi...
