It has two main contributions: First, unlike previous structural approaches that use a single graph for representing a tissue image, it proposes to obtain a set of subgraphs through graph walking and use these subgraphs in representing the image. Second, it proposes to characterize subgraphs by directly using distribution of their edges, instead of employing conventional global graph features, and use these characterizations in classification. Our experiments on colon tissue images reveal that the proposed structural approach is effective to obtain high accuracies in tissue image classification. © 2013 IEEE.EnglishGraphsAutomated cancer diagnosisGraphsHistopathological image analysisSubgraphsMedical imagingTissueTissue engineeringImage classificationConference Paper10.1109/ISBI.2013.6556677
