Introduction to CelloType
Cell segmentation and classification are crucial for understanding cellular structures and functions. With recent advancements in spatial omics technologies, we can achieve high-resolution analysis of tissues. This supports important projects like the Human Tumor Atlas Network. Traditional methods often treat segmentation and classification as separate tasks, leading to inefficiencies and inconsistencies.
Challenges with Traditional Methods
Convolutional Neural Networks (CNNs) have made progress, but they still struggle with integrating semantic information in tissue images. Newer transformer-based models, like DINO and MaskDINO, show better performance in biomedical imaging but need further exploration in cell segmentation. Unique challenges arise with multiplexed images due to their complexity.
