Evaluation Metrics for Medical Organ Segmentation and Lesion Detection
Abdel Aziz Taha, Allan Hanbury · 2017
This chapter provides an overview of the metrics used in the VISCERAL segmentation benchmarks, namely Anatomy 1, 2 and 3. In particular, it provides an overview of 20 evaluation metrics for segmentation, from which four metrics were selected to be used in VISCERAL benchmarks. It also provides an analysis of these metrics in three ways: first by analysing fuzzy implementations of these metrics using fuzzy segmentations produced either synthetically or by fusing participant segmentations and second by comparing segmentation rankings produced by these metrics with rankings performed manually by radiologists. Finally, a metric selection is performed using an automatic selection framework, and the selection result is validated using the manual rankings. Furthermore, this chapter provides an overview of metrics used for the Lesion Detection Benchmark. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
