Latest Patents
One of Ligong Han's latest patents is titled "Video synthesis via multimodal conditioning." This patent presents a multimodal video generation framework (MMVID) that utilizes text and images as input, either jointly or separately. The framework employs quantized representations of videos and a bidirectional transformer to predict discrete video representations. It incorporates a new video token trained with self-learning and an improved mask-prediction algorithm to enhance video quality and consistency. Additionally, text augmentation is utilized to improve the robustness of textual representation and the diversity of generated videos. The MMVID framework also integrates various visual modalities, such as segmentation masks, drawings, and partially occluded images, while extracting visual information based on textual prompts.
Another significant patent is "Learning orthogonal factorization in GAN latent space." This method focuses on learning disentangled representations of videos. It involves feeding each frame of video data into an encoder to produce a sequence of visual features. These features are then processed through a deep convolutional network to obtain posteriors of dynamic and static latent variables. The method samples representations from these posteriors and concatenates them for reconstruction. To facilitate disentangled sequential representation learning, orthogonal factorization in generative adversarial network (GAN) latent space is leveraged to pre-train a generator as a decoder.
