Labial Teeth and Gingiva Image DatabaseThe LTG-IDB currently contains 90 photographic digital still images from 27 subjects. Images are available in several sets that differ by resolution, file format and image scene type. This leads to a total of 405 images occupying about 7GB of memory.
Images in this database are available in raw image format (which is the unprocessed sensor data of the camera in a specific vendor dependent data format, in this case the Canon raw image format cr2), as well as JPEG and TIFF. The strengths of this database are the fixed, well-defined and well known parameters of image acquisition. In addition, the variety of analytical and methodological applications shall be highlighted, as this database includes raw images, as well as pre-processed JPEG and TIFF images and is published under a creative common license.
A detailed description on the properties
of this databse is given in T. Eckhard, E. Valero, J. Nieves, F. Mesa, "The Labial Teeth and Gingiva Photographic Image Database LTG-IDB, technical report", 2011 .
