Generating synthetic digital images utilizing a text-to-image generation neural network with localized constraints

Abstract

Methods, systems, and non-transitory computer readable storage media are disclosed for generating digital images via a generative neural network with localized constraints. The disclosed system generates, utilizing one or more encoder neural networks, a sequence of embeddings comprising a prompt embedding representing a text prompt and an object text embedding representing a phrase indicating an object in the text prompt. The disclosed system generates, utilizing the one or more encoder neural networks, a visual embedding representing an object image corresponding to the object. The disclosed system determines a modified sequence of embeddings by replacing the object text embedding with the visual embedding in the sequence of embeddings. The disclosed system also generates, utilizing a generative neural network, a synthetic digital image from the modified sequence of embeddings comprising the visual embedding.
