Existing facial databases cover large variations including: different subjects, poses, illumination, occlusions etc. However, the provided annotations appear to have several limitations.
Figure 1: (a)-(d) Annotated images from MultiPIE, XM2VTS, AR, FRGC Ver.2 databases, and (e) examples from XM2VTS with inaccurate annotations.
- The majority of existing databases provide annotations for a relatively small subset of the overall images.
- The accuracy of provided annotations in some cases is not so good (probably due to human fatigue).
- The annotation model of each database consists of different number of landmarks.
These problems make cross-database experiments and comparisons between different methods almost infeasible. To overcome these difficulties, we propose a semi-automatic annotation methodology for annotating massive face datasets. This is the first attempt to create a tool suitable for annotating massive facial databases.
All the annotations are provided for research purposes ONLY (NO commercial products).

We employed our tool for creating annotations (following the Multi-PIE 68 points mark-up, please see Fig. 2) for the following databases:
