We continually train a pre-trained T2V models via block expansion and LLMs conditioning.

We propose a pixel-wise control framework based on unconditional diffusion models for the degradation-blind inverse problems with the performance of semantic consistency and details preservation.

We propose an image assessment metric presenting human's like based on Instagram dataset.

We propose an automatic framework enabling agile development of detection models and human-in-the-loop annoation.
