Model Card for FollowYourPose V1

Model Details

Model Description

The authors note in the assoicated paper:

Pose-Guided Text-to-Video Generation. We propose an efficient training scheme to empower the ability of the pretrained text-to-image model (i.e., Stable Diffusion) to generate pose-controllable character videos with minimal data requirements. We can generate various high-definition pose-controllable character videos that are well-aligned with the pose sequences and the semantics of text prompts.

Uses

Direct Use

Text to Video

Downstream Use

• Character replacement
• Background change
• Style transfer
• Multiple characters

Out-of-Scope Use

Note: This section as adpated from the Stable Diffusion v1 model card. The model was not trained to be factual or true representations of people or events, and therefore using the model to generate such content is out-of-scope for the abilities of this model.

Bias, Risks, and Limitations

Note: This section is adpted from the DALLE-MINI model card.

The model should not be used to intentionally create or disseminate videos that create hostile or alienating environments for people. This includes generating videos that people would foreseeably find disturbing, distressing, or offensive; or content that propagates historical or current stereotypes.

Recommendations

Users (both direct and downstream) should be made aware of the risks, biases and limitations of the model. More information needed for further recommendations.

Training Details

Training Data

Stage 1 Training Data: Pose-Controllable Text-to-Image Gen- eration. The authors note in the assoicated paper that they colected

the human skeleton images in the LAION by Mpose, only retaining images that could be detected more than 50% of the key point which formed a dataset named LAION-Pose from.

The autheors note in the associated paper about LAION-Pose:

This dataset contains diverse human-like characters with various back- ground contexts.

Stage 2 Training Data: Video Generation via Pose-free Videos.

However, the stage 1 model can generate similar pose videos yet the background is inconsistent. Thus, we further finetune the model from our first stage on the pose- free video dataset HDVLIA This dataset contains con- tinuous in-the-wild video text pairs.

Training Procedure

Preprocessing

The authors note in the assoicated paper:

We learn a zero-initialized convolutional encoder to encode the pose information We finetune the motion of the above network via a pose-free video dataset by adding the learnable temporal self-attention and reformed cross-frame self-attention blocks.

Metrics

The authors note in the assoicated paper:

• CLIP score (CS): CLIP score or video-text alignment. We compute CLIP score for each frame and then average them across all frames. The final CLIP score is calculated on 1024 video samples.
• Quality (QU): We conduct the human evaluation of videos’ quality across a test set containing 32 videos. In detail, we display three videos in random order and request the evaluators to iden- tify the one with superior quality
• Pose Accuracy (FQ): We regard the input pose sentence as ground truth video and evaluate the average precision of the skeleton on 1024 video samples. For a fair comparison, we adopt the same pose detector for both the processing of LAION-Pose collecting and evaluation.
• Frame Consistency (FC): Following we report frame consistency measured via CLIP cosine similarity of consecutive frames

Model Architecture and Objective

The authors note in the assoicated paper:

To make the pre-trained T2I model suitable for video inputs, we make several key modifications. Firstly, we add extra temporal self-attention layers, to the stable diffusion network. Secondly, inspired by the recent one-shot video generation model, we reshape the attention to cross-frame attention for better content consistency.
