Abstract(in English) | Manual annotation in image segmentation is time-consuming and expensive. In order to obtain large number of annotated data set efficiently, Bayesian active learning has been proposed. The key component in the iteration in Bayesian active learning is the selection of query slices (or voxels) which maximize the performance of the model trained in the next iteration. We need to take account for (1) uncertainty estimated from the model trained in the previous iteration, i.e., the distance from the existing training data set, and (2) similarity among the query images. The large batch acquisition with diverse images far from the existing data set enables higher efficiency in active learning. In this study, we investigated the performance and efficiency of several Bayesian active learning approaches specifically for segmentation of liver and spleen in a realistic simulation study using 251 fully annotated abdominal MR data set. |
