The BioID Face Database ======================= http://www.bioid.com/support/downloads/software/bioid-face-database.html Files ===== BioID-FD-Eyepos-V1.2.zip Corresponding Eye-Positions files BioID-FaceDatabase-V1.2.zip The BioID Face Database itself bioid_pts.zip FGnet Markup Scheme of the BioID Face Database Description =========== The BioID Face Database has been recorded and is published to give all researchers working in the area of face detection the possibility to compare the quality of their face detection algorithms with others. During the recording special emphasis has been laid on "real world" conditions. Therefore the testset features a large variety of illumination, background and face size. The dataset consists of 1521 gray level images with a resolution of 384x286 pixel. Each one shows the frontal view of a face of one out of 23 different test persons. For comparison reasons the set also contains manually set eye postions. The images are labeled "BioID_xxxx.pgm" where the characters xxxx are replaced by the index of the current image (with leading zeros). Similar to this, the files "BioID_xxxx.eye" contain the eye positions for the corresponding images. Image File Format ================= The images are stored in single files using the portable gray map (pgm) data format. A pgm file contains a data header followed by the image data. In our case the header consists of four lines of text. * The first line describes the format of the image data (ASCII/binary). In our files the text "P5" indicates that the data is written in binary form * The second line contains the image width written in text form * The third line keeps the image height also in text form * The fourth line contains the maximum allowed gray value (255 in our images) The header is followed by a data block containing the image data. The data is stored line per line from top to bottom using one byte per pixel. Eye Position File Format ======================== The eye position files are text files containing a single comment line followed by the x and the y coordinate of the left eye and the x and the y coordinate of the right eye separated by spaces. Note that we refer to the left eye as the person's left eye. Therefore, when captured by a camera, the position of the left eye is on the image's right and vice versa. FGnet Markup Scheme of the BioID Face Database ============================================== The BioID Face Database is being used within the FGnet project of the European Working Group on face and gesture recognition. David Cristinacce and Kola Babalola, PhD students from the department of Imaging Science and Biomedical Engineering at the University of Manchester marked up the images from the BioID Face Database. They selected several additional feature points, which are very useful for facial analysis and gesture recognition.
