Spiral Reverse classification accuracy predicting segmentation performance

In this paper we introduce the concept of reverse classification accuracy RCA as a framework for predicting the performance of a segmentation method on new data In RCA we take the predicted segmentation from a new image to train a reverse classifier which is evaluated on a set of reference images with available ground truth.
