DiffusionLoc: A diffusion model-based framework for crowd localization

Qi Zhang, Yuan Li, Yiran Liu, Yanzhao Zhou, Jianbin Jiao

Abstract: Highlights•Formulate point localization as a noise-to-point denoising process.•Eliminate reliance on heuristic priors, boosting efficiency and adaptability.•Pioneer the use of diffusion models for crowd localization frameworks.•Design a robust feature interpolation method in noisy scenes by differential attention.•Achieve competitive accuracy and flexibility across five benchmark datasets.
