Abstract

The purpose of this paper is to introduce a tool that provides a GUI for generating a ground truth for landmark positions for 2D images used in computer vision applications. Further, we demonstrate via a case study that this tool greatly improves manual landmarking in the case of extremely dense (more than 250 points per images) annotation of face images with a factor of two speed up. Moreover the tool incorporates workflow technology capable of allowing multiple land-markers to work on the same set of images and for quality assurance checks. We are in the process of making this tool freely available to researchers from academia.
