ZoomLDM: Latent Diffusion Model for Multi-scale Image Generation

CVPR 2025poster

Diffusion models have revolutionized image generation, yet several challenges restrict their application to large-image domains, such as digital pathology and satellite imagery. Given that it is infeasible to directly train a model on 'whole' images from domains with potential gigapixel sizes, diffu…

∞-Brush: Controllable Large Image Synthesis with Diffusion Models in Infinite Dimensions

ECCV 2024poster

"Synthesizing high-resolution images from intricate, domain-specific information remains a significant challenge in generative modeling, particularly for applications in large-image domains such as digital histopathology and remote sensing. Existing methods face critical limitations: conditional dif…

Topology-Guided Multi-Class Cell Context Generation for Digital Pathology

CVPR 2023poster

In digital pathology, the spatial context of cells is important for cell classification, cancer diagnosis and prognosis. To model such complex cell context, however, is challenging. Cells form different mixtures, lineages, clusters and holes. To model such structural patterns in a learnable fashion,…

Multi-Class Cell Detection Using Spatial Context Representation

ICCV 2021poster

In digital pathology, both detection and classification of cells are important for automatic diagnostic and prognostic tasks. Classifying cells into subtypes, such as tumor cells, lymphocytes or stromal cells is particularly challenging. Existing methods focus on morphological appearance of individu…
