Abstract: A computer-implemented method for generating an image involves receiving input text and layout information, decomposing the text into global and local features, and encoding these features into vectors. The method initializes an initial image representation and uses a trained neural network to predict global noise from the global vector and initial image representation. It also predicts initial local noise for each local feature using their respective vectors and the initial image representation. The final local noise for each feature is determined using the initial local noise and the global noise. The predicted global and final local noises are combined based on the layout information. Finally, the initial image representation is denoised using this combined noise to produce the next image representation, ultimately generating the image.
