abstract: Acquiring a comprehensive segmentation map of the retinal image serves as the preliminary step in developing an interpretable diagnostic tool for retinopathy. However, the inherent complexity of retinal anatomical structures and lesions, along with data heterogeneity and annotations scarcity, poses challenges to the development of accurate and generalizable models. Denoising diffusion probabilistic models (DDPM) have recently shown promise in various medical image applications. In this paper, driven by the motivation to leverage strong pre-trained DDPM, we introduce a novel framework, named DiffDGSS, to exploit the latent representations from the diffusion models for Domain Generalizable Semantic Segmentation (DGSS). In particular, we demonstrate that the deterministic inversion of diffusion models yields robust representations that allow for strong out-of-domain generalization. Subsequently, we develop an adaptive semantic feature interpreter for projecting these representations into an accurate segmentation map. Extensive experiments across various tasks (retinal lesion and vessel segmentation) and settings (cross-domain and cross-modality) demonstrate the superiority of our DiffDGSS over state-of-the-art methods.
