Assessing Data Quality of Annotations with Krippendorff Alpha For Applications in Computer Vision

no code implementations20 Dec 2019 Joseph Nassar, Viveca Pavon-Harr, Marc Bosch, Ian McCulloh

In this paper we studied this problem for object detection and recognition. We conducted several data annotation experiments to measure inter annotator agreement and consistency, as well as how the selection of ground truth impacts the perceived algorithm performance. We propose a methodology to monitor the quality of annotations during the labeling of images and how it can be used to measure performance.
