New CORE engine enables precise cell-level image registration for multi-stain slides

By PulseAugur Editorial · [1 sources] · 2026-07-21 04:00

Researchers have developed CORE, a novel coarse-to-fine image registration engine designed for aligning multi-stained tissue slides at the cellular level. The framework employs a two-stage process: initial coarse registration uses tissue masks and feature matching for global alignment, followed by fine-grained rigid and non-rigid registration of nuclei using point-set models and Coherent Point Drift. This method aims to improve accuracy, generalizability, and robustness in analyzing whole slide images across different microscopy modalities. AI

IMPACT Enhances precision in biological image analysis, potentially accelerating drug discovery and diagnostic research.

CORE -- A Cell-Level Coarse-to-Fine Image Registration Engine for Multi-stain Image Alignment

arXiv:2511.03826v4 Announce Type: replace-cross Abstract: Accurate and efficient registration of whole slide images (WSIs) is essential for high-resolution, nuclei-level analysis in multi-stained tissue slides. We propose a novel coarse-to-fine framework CORE for accurate nuclei-…
