QCell model improves overlapping cell segmentation in microscopy images

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced QCell, a novel query-based model designed to improve instance segmentation of overlapping cells in microscopy images. This new approach addresses the challenge of weak boundaries and mixed visual evidence in overlap regions by incorporating an instance recombination module for latent space reasoning and a contrastive query alignment objective to separate overlapping cell queries. QCell demonstrates superior performance compared to existing methods, achieving significant improvements in Average Precision (AP) and Adjusted Rand Index (AJI) on the ISBI2014 benchmark, and is accompanied by a new Organoid dataset for benchmarking.

    QCell: Recombining and Aligning Cell Queries for Overlapping Instance Segmentation

    arXiv:2608.29253v1 Announce Type: cross Abstract: Instance segmentation of overlapping cells in microscopy remains challenging due to semi-transparent structures that produce weak boundaries and mixed visual evidence in overlap regions. Existing methods address this through local…
