Abstract

The invention discloses a dual learning-based cross-modal text video generation method and system, and the method comprises the following steps: constructing a text-to-video generation model; constructing a video-to-text mapping model; utilizing a dual learning mechanism to jointly train the generation model and the mapping model to obtain a training model; inputting preset characters into the training model to generate a corresponding initial video; and mapping the initial video into new characters by utilizing the mapping model, and feeding back the new characters to the generation model tojudge whether the new characters are matched with preset characters or not, and then repairing the initial video to obtain a final mapped video. The bidirectional mapping between the text informationand the video information is considered, so that the text-to-video generation is better realized, and meanwhile, the generated video is higher in quality and higher in matching degree with user requirements.

Description

technical field [0001] The invention relates to the technical field of multi-modal generation models, in particular to a method and system for generating video from cross-modal text based on dual learning. Background technique [0002] Currently, user experience is very important in terms of language and visual interaction scenarios between users and machines. The user inputs text or language, and the machine can generate corresponding videos according to the user input, but there are still some problems in whether the generated video is realistic and whether it is consistent with the user input. For example, the existing method of generating video from text only considers the one-way mapping from text to video, maps text data and video data to the same latent space, and then reconstructs the video according to the data points in the latent space to achieve the purpose of generating video from text . At the technical level, the specific steps are to map the text to the lat...
