TOSCA highresolution MATLAB (75MB)  ASCII (65MB)  License
Hiresolution threedimensional nonrigid shapes in a variety of poses
for nonrigid shape similarity and correspondence experiments. The database
contains a total of 80 objects, including 11 cats, 9 dogs, 3 wolves, 8 horses,
6 centaurs, 4 gorillas, 12 female figures, and two different male figures, containing 7
and 20 poses. Typical vertex count is about 50,000. Objects within the same class have
the same triangulation and an equal number of vertices numbered in a compatible way.
This can be used as a pervertex ground truth correspondence in correspondence experiments.
Two representations are available: MATLAB file (.mat) and ASCII text files
containing the 1based list of triangular faces (.tri), and a list of vertex
XYZ coordinates (.vert). A .png thumbnail is available for each object.

Threedimensional nonrigid shapes in a variety of poses for nonrigid shape similarity and correspondence experiments. The database contains a total of 148 objects, including 9 cats, 11 dogs, 3 wolves, 17 horses, 15 lions, 21 gorillas, 1 shark, 24 female figures, and two different male figures, containing 15 and 20 poses. The database also contains 6 centaurs, and 6 seahorses for partial similarity experiments. Each object contains approximately 3000 vertices. Two representations are available: MATLAB file (.mat) and ASCII text files containing the 1based list of triangular faces (.tri), and a list of vertex XYZ coordinates (.vert). A .png thumbnail is available for each object.

Human face .zip (2.9MB)  License
An animated threedimensional face showing different facial expressions, acquired using a realtime range camera. The acquisition speed is approximately 3 frames/sec. The database contains 15 expressions of the same face, represented as a textured shape. Each object contains approximately 2000 vertices. Two representations are available: MATLAB file (.mat) and ASCII text files containing the 1based list of triangular faces (.tri), a list of vertex XYZ coordinates (.vert), and a list of [0...1] texture intensity levels (.text). A .png thumbnail is available for each object. A MATLAB function for reading the data is supplied.
