Highly realistic synthetic dataset for pixel-level DensePose estimation via diffusion model

Generating training data with pixel-level annotations for DensePose is a labor-intensive task, resulting in sparse labeling in real-world datasets. Prior solutions have relied on specialized data generation systems to synthesize datasets. However, these synthetic datasets often lack realism and rely on expensive resources such as human body models and texture mappings. In this paper, we address these challenges by introducing a novel data generation method based on the diffusion model, effectively producing highly realistic data without the need for expensive resources. Specifically, our method comprises annotation generation and image generation. Utilizing graphic renderers and SMPL models, we produce synthetic annotations solely based on human poses and shapes. Subsequently, guided by these annotations, we employ simple yet effective textual prompts to generate a wide range of realistic images using the diffusion model. Our experiments conducted on DensePose-COCO dataset demonstrate the superiority of our method compared to existing methods. Code and benchmarks will be released.
