VISCERAL — VISual Concept Extraction challenge in RAdioLogy: ISBI 2014 Challenge Organization

The VISual Concept Extraction challenge in RAdioLogy (VISCERAL) project has been developed as a cloud–based infrastructure for the evaluation of medical image data in large data sets. As part of this project, the ISBI 2014 (Inter-national Symposium for Biomedical Imaging) challenge was organized using the VISCERAL data set and shared cloud– framework. Two tasks were selected to exploit and com-pare multiple state–of–the–art solutions designed for big data medical image analysis. Segmentation and landmark localiza-tion results from the submitted algorithms were compared to manually annotated ground truth in the VISCERAL data set. This paper presents an overview of the challenge setup and data set used as well as the evaluation metrics from the vari-ous results submitted to the challenge. The participants pre-sented their algorithms during an organized session at ISBI 2014. There were lively discussions in which the importance of comparing approaches on tasks sharing a common data set was highlighted. Copyright c © by the paper’s authors.
