Method for generating an image from a textual instruction, and associated computer program and system

Abstract

Method for generating an image from a textual instruction, and associated computer program and system. The present invention relates to a method for generating an image from a textual instruction, comprising the following steps: - initialization (120) of an image by random noise; - inverse diffusion (140, 240) of the image comprising the following sub-steps: - calculation (141, 241) of a plurality of attention maps using a pre-trained diffusion model; - semantic guidance (142, 242) from the attention maps; The method is characterized in that it further comprises a step of decomposing the image into a low-frequency image and a high-frequency image, and in that during at least certain iterations of the inverse diffusion step (140), called improved iterations, the semantic guidance (142) is implemented only on the low-frequency image.
