Abstract

The embodiment of the invention provides a training method of an image generation model, a generation method and device and equipment, and relates to the technical field of machine learning and image processing. The training method comprises the steps that a first transformation model is obtained through training, the first transformation model is used for generating a first training image based on a first noise sample, and the first training image is an image of a first type of style; training is performed to obtain a reconstruction model based on the first transformation model; a second transformation model is obtained through training, the second transformation model is used for generating a second training image based on the second noise sample, and the second training image is an image of a second type of style; the first transformation model and the second transformation model are grafted to generate a grafted transformation model; and based on the reconstruction model and the grafted transformation model, an image generation model is generated, and the image generation model is used for transforming the to-be-transformed image of the first type of style into a target image of a second type of style. By adopting the technical scheme provided by the embodiment of the invention, the time cost of model training can be reduced.

Description

technical field [0001] The embodiments of the present application relate to the technical field of machine learning and image processing, and in particular to a training method, generation method, device and equipment for an image generation model. Background technique [0002] At present, machine learning technology is more and more widely used in the field of image processing technology, for example, transforming the style of an image based on machine learning technology. [0003] In related technologies, a large number of training sample pairs are collected first, and each training sample pair includes a real face image and a corresponding face caricature image; The completed learned model is the image generation model. [0004] In the above-mentioned related technologies, the face caricature image generated by the image generation model must not only maintain the face features, but also have a relatively strong caricature style, so it is necessary to use a large number ...
