The CRIC Cervix Collection: A new, open-source, searchable image database for predictive modeling and screening

June 16, 2021

BIDS Research Affiliate Daniela Ushizima and colleagues from the Center for Recognition and Inspection of Cells (CRIC) have published the CRIC Cervix Collection, a searchable image database that makes digital cell image collections available for reproducible research and FAIR machine learning.

This free and open-source digital platform  consists of real images of conventional cervical-vaginal cytology, obtained from the Pap smear, which were classified by specialists according to the Bethesda System (standardized nomenclature). The CRIC Cervix Collection is the largest available database of cervical cells obtained from conventional smears, which stands out in terms of both the total number of cells (11,534 identified and manually classified) and the number of cells per class of lesion, thus providing greater variety from pre-neoplastic and neoplastic lesions to conventional cervico-vaginal cytology.

The classifications were performed and certified by cytopathologists from the Laboratory of Cytology of the Department of Clinical Analysis, School of Pharmacy, and the digital platform was implemented by experts from the Department of Computer Science, both at the Federal University of Ouro Preto (UFOP) in Brazil. Other contributors have come from three main institutions: Federal University of Ceara, University of California, Berkeley, and Lawrence Berkeley National Laboratory.

Through the Moore-Sloan Foundations, BIDS has provided invaluable support for research and development projects since CRIC's inception, and has hosted several CRIC researchers. The database has been used by several CRIC teams, in Brazil (UFOP, UFC, IFCE and UFPI) and abroad, to develop machine and deep learning methodologies to detect, identify and classify lesions among cervical cells, such as in this other recent science article (A Hierarchical Feature-Based Methodology to Perform Cervical Cancer Classification, MDPI Applied Science, 2021) by the CRIC team. Enabling predictive modeling using biomedical data and computer-aided diagnosis are some of the goals of CRIC. Watch this video for a quick journey into the CRIC way of looking at cancer cells.
