Abstract: The present disclosure provides systems and methods for video generation using latent diffusion machine learning models. Given a text input, video data relevant to the text input can be generated using a latent diffusion model. The process includes generating a predetermined number of key frames using text-to-image generation tasks performed within a latent space via a variational auto-encoder, enabling faster training and sampling times compared to pixel space-based diffusion models. The process further includes utilizing two-dimensional convolutions and associated adaptors to learn features for a given frame. Temporal information for the frames can be learned via a directed temporal attention module used to capture the relation among frames and to generate a temporally meaningful sequence of frames. Additional frames can be generated via a frame interpolation process for inserting one or more transition frames between two generated frames.

Abstract: Automatic data generation includes extracting latent features from an input image, adding a perturbation to the latent features, applying the perturbed latent features to a pre-trained generative model, and training an image generator with images output from the generative model.

Abstract: Generating an object using a diffusion model includes obtaining a first input and a second input, and synthesizing an output object from the first input and the second input. The synthesizing of the output object includes generating a layout of the output object from the first input, injecting the second input as a content conditioner to the layout of the output object, and de-noising the layout of the output object injected with the content conditioner to generate a content of the output object.
