Abstract:
The National Library of Medicine (NLM), in collaboration with the National Cancer Institute (NCI), is
creating a large digital repository of cervicographic images for the study of uterine cervix cancer
prevention. One of the research goals is to automatically detect diagnostic bio-markers in these images.
Reliable bio-marker segmentation in large biomedical image collections is a challenging task due to the
large variation in image appearance. Methods described in this paper focus on segmenting mosaicism,
which is an important vascular feature used to visually assess the degree of cervical intraepithelial
neoplasia. The proposed approach uses support vector machines (SVM) trained on a ground truth dataset
annotated by medical experts (which circumvents the need for vascular structure extraction). We have
evaluated the performance of the proposed algorithm and experimentally demonstrated its feasibility.
